update release workflow

* 0.3.4

* Add `RequestOptions` for per-request customization with headers and timeouts

- Introduced the `RequestOptions` struct for flexible HTTP request configurations.
- Added `request_with_options` and `post_with_options` methods.
- Deprecated `request` and `post` in favor of the new methods.
- Updated examples and tests to reflect the new API.

* run cargo fmt

* Update HTTP client methods to use `request_with_options` for improved flexibility. Adjusted related test cases and examples accordingly.

* Format `request_with_options` calls for improved readability.

* - Downgrade `edition` from 2024 to 2021 in Cargo.toml files for compatibility.
- Fix nested `if let` statements to improve readability and correctness.
- Reorganize imports for consistency and structure.

* Restore github old workflows

* update ci

+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+

+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (which shall not include communications that are conspicuously
+      marked or otherwise designated in writing by the copyright owner
+      as "Not a Contribution").
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to use, reproduce, modify, publicly display,
+      publicly perform, sublicense, and distribute the Work and such
+      Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, trademark, patent,
+          attribution and other notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright notice and additional terms or conditions
+      for use, reproduction, or distribution of Your Work or for any such
+      Derivative Works as a whole, provided Your use, reproduction, and
+      distribution of the Work otherwise complies with the conditions stated
+      in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Support. When redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional support.
+
+   END OF TERMS AND CONDITIONS

-A reusable HTTP client builder API with clear, security‑focused feature flags for selecting your TLS backend and security posture.
+A small, ergonomic HTTP client wrapper around hyper with optional support for custom Root CAs and a dev-only insecure mode for self-signed certificates.
 
-This crate is derived from a reference implementation in this repository (under `reference-implementation/`), but is designed as a reusable library with a more robust and explicit configuration surface. Networking internals are intentionally abstracted for now; the focus is on a secure, ergonomic API.
+## Features
 
-## Features and TLS strategy
+- **Secure by Default**: Uses the operating system's native trust store via `native-tls`
+- **Custom CA Support**: Optional `rustls` feature for connecting to services with custom Certificate Authorities
+- **Development Mode**: Optional `insecure-dangerous` feature for testing with self-signed certificates (⚠️ **NEVER use in production**)
+- **WebAssembly Compatible**: Proper WASM support with appropriate security constraints
+- **Certificate Pinning**: Advanced security feature for production environments
+- **Builder Pattern**: Ergonomic configuration with sensible defaults
 
-- Default: `native-tls`
+## Quick Start
-  - Uses the operating system trust store via `hyper-tls`/`native-tls`.
-  - Secure default for connecting to standard, publicly trusted endpoints.
 
-- Optional: `rustls`
+`cargo add hyper-custom-cert`
-  - Uses `hyper-rustls`.
-  - Activates the `with_root_ca_pem` method on the builder, allowing you to trust a custom Root CA (recommended approach for custom/private CAs).
 
-- Optional: `insecure-dangerous`
+### Basic Usage (Secure Default)
-  - Unlocks `insecure_accept_invalid_certs(true)` and `HttpClient::with_self_signed_certs()`.
-  - IMPORTANT: This is for local development/testing only and must NEVER be used in production.
 
-See SECURITY.md for a thorough discussion of these modes and when to use them.
+```rust
+use hyper_custom_cert::HttpClient;
 
-## Quick start
+#[tokio::main]

-## Builder API overview
+### Certificate Pinning (Enhanced Security)
 
-```rust,ignore
+For high-security environments where you want to pin specific certificates:
+
+```rust
+use hyper_custom_cert::HttpClient;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // SHA-256 fingerprints of certificates you want to accept
+    let pin1 = [0x12, 0x34, /* ... 30 more bytes */];
+    let pin2 = [0xab, 0xcd, /* ... 30 more bytes */];
+    
+    let client = HttpClient::builder()
+        .with_pinned_cert_sha256(vec![pin1, pin2])
+        .build();
+    
+    // Only accepts connections to certificates matching the pins
+    client.request("https://secure-api.example.com").await?;
+    
+    Ok(())
+}
+```
+
+### Development/Testing Only (⚠️ Dangerous)
+
+**WARNING**: This mode disables certificate validation. Only use for local development and testing.
+
+```toml
+[dependencies]

-
-## Selecting features
-
-- Native TLS (default):
-  - `cargo add hyper-custom-cert` (or no extra flags if in this workspace)
-  - `cargo build`
-
-- Rustls:
-  - `cargo build --no-default-features --features rustls`
-
-- Insecure (dangerous, dev only):
-  - With native TLS: `cargo build --features insecure-dangerous`
-  - With rustls: `cargo build --no-default-features --features rustls,insecure-dangerous`
-
-## WASM Support
-
-This library's WASM build is **primarily intended for edge runtime environments** such as Cloudflare Workers, Deno Deploy, Vercel Edge Functions, and similar serverless edge computing platforms.
-
-### Edge Runtime Usage (Primary Use Case)
-
-Edge runtimes provide a more capable WASM environment compared to browsers, often supporting custom certificate configuration and advanced TLS features:
-
-**Capabilities in Edge Runtimes:**
-- **Custom Root CA Support:** Methods like `with_root_ca_pem()` and `with_root_ca_file()` are typically supported
-- **Certificate Pinning:** The `with_pinned_cert_sha256()` method may be available depending on the runtime
-- **Flexible TLS Configuration:** Full control over certificate validation and TLS settings
-- **No Same-Origin Policy:** Direct network access without browser security restrictions
-
-**Recommended Approach for Edge Runtimes:**
-```rust,ignore
-#[cfg(target_arch = "wasm32")]
-{
-    // For edge runtimes, full custom CA support is typically available
-    #[cfg(feature = "rustls")]
 let client = HttpClient::builder()
-        .with_timeout(Duration::from_secs(10))
+    .with_timeout(Duration::from_secs(30))
-        .with_root_ca_pem(include_bytes!("../certs/root-ca.pem"))
+    .with_default_headers(headers)
+    .with_root_ca_file("custom-ca.pem")  // Requires 'rustls' feature
     .build();
+```
 
-    // Certificate pinning for additional security
+### Available Methods
-    let pin: [u8; 32] = [/* your certificate SHA-256 hash */];
+
-    let client_with_pinning = HttpClient::builder()
+| Method | Feature Required | Description |
-        .with_pinned_cert_sha256(vec![pin])
+|--------|-----------------|-------------|
-        .build();
+| `new()` | None | Creates client with OS trust store (secure default) |
+| `builder()` | None | Returns a builder for custom configuration |
+| `with_timeout(Duration)` | None | Sets request timeout |
+| `with_default_headers(HashMap)` | None | Sets default headers for all requests |
+| `with_root_ca_pem(&[u8])` | `rustls` | Adds custom CA from PEM bytes |
+| `with_root_ca_file(Path)` | `rustls` | Adds custom CA from PEM file |
+| `with_pinned_cert_sha256(Vec<[u8; 32]>)` | `rustls` | Enables certificate pinning |
+| `insecure_accept_invalid_certs(bool)` | `insecure-dangerous` | ⚠️ Disables certificate validation |
+| `with_self_signed_certs()` | `insecure-dangerous` | ⚠️ Convenience for self-signed certs |
+
+## Feature Flags
+
+### `native-tls` (Default)
+
+- **Default**: ✅ Enabled
+- **Security**: ✅ Secure - Uses OS trust store
+- **Use Case**: Public HTTPS endpoints with standard certificates
+- **Dependencies**: `hyper-tls`, `native-tls`
+
+### `rustls`
+
+- **Default**: ❌ Disabled
+- **Security**: ✅ Secure - Custom CA validation
+- **Use Case**: Private/custom Certificate Authorities
+- **Dependencies**: `hyper-rustls`, `rustls-pemfile`
+- **Enables**: `with_root_ca_pem()`, `with_root_ca_file()`, `with_pinned_cert_sha256()`
+
+### `insecure-dangerous`
+
+- **Default**: ❌ Disabled
+- **Security**: ❌ **EXTREMELY DANGEROUS**
+- **Use Case**: **Development/testing ONLY**
+- **Warning**: **NEVER enable in production**
+- **Enables**: `insecure_accept_invalid_certs()`, `with_self_signed_certs()`
+
+## WebAssembly (WASM) Support
+
+This crate supports WebAssembly targets with important security considerations:
+
+```rust
+// WASM builds will compile, but certain operations are restricted
+#[cfg(target_arch = "wasm32")]
+{
+    let client = HttpClient::new(); // ✅ Works
+    // Custom CA operations may return WasmNotImplemented errors
 }
 ```
 
-**Popular Edge Runtime Platforms:**
+**WASM Limitations:**
-- **Cloudflare Workers:** Full WASM support with network capabilities
+- Custom Root CA installation requires browser/OS-level certificate management
-- **Deno Deploy:** TypeScript/JavaScript runtime with WASM modules
+- Some TLS configuration options may not be available
-- **Vercel Edge Functions:** Next.js edge runtime environment  
+- Certificate pinning may be limited by browser security policies
-- **Fastly Compute@Edge:** High-performance edge computing platform
-- **AWS Lambda@Edge:** Serverless edge functions
 
-### Browser Usage (Limited Support)
+**Browser Certificate Installation:**
+1. Download your organization's Root CA certificate
+2. Install it in your browser's certificate store
+3. Mark it as trusted for websites
+4. Your WASM application will then trust endpoints signed by that CA
 
-When running in browser environments, WASM operates under significant security restrictions:
+## Error Handling
 
-**Browser Limitations:**
+```rust
-- **No Custom Root CA Support:** Methods like `with_root_ca_pem()` and `with_root_ca_file()` may return `WasmNotImplemented` errors
+use hyper_custom_cert::{HttpClient, ClientError};
-- **No Certificate Pinning:** The `with_pinned_cert_sha256()` method is not available in browser environments
-- **Browser-Controlled Trust:** All certificate validation is handled by the browser's built-in certificate store
-- **Same-Origin Policy:** Cross-origin requests are subject to CORS policies and browser security models
 
-**Browser Development Guidance:**
+match client.request("https://example.com").await {
-```rust,ignore
+    Ok(_) => println!("Request successful"),
-#[cfg(target_arch = "wasm32")]
+    Err(ClientError::WasmNotImplemented) => {
-{
+        println!("This operation isn't supported in WASM");
-    // For browser WASM, rely on browser's built-in certificate validation
+    }
+    Err(e) => {
+        println!("Request failed: {}", e);
+    }
+}
+```
+
+## Security Best Practices
+
+### Production Recommendations
+
+1. **Use Default Mode**: Stick with `native-tls` for public endpoints
+2. **Custom CA Only When Needed**: Only use `rustls` feature when connecting to private CAs
+3. **Never Use `insecure-dangerous`**: This feature should never be enabled in production
+4. **Keep Dependencies Updated**: Monitor for security advisories
+5. **Certificate Pinning**: Consider pinning for high-security applications
+
+### Development vs Production
+
+```rust
+// ✅ GOOD: Production configuration
+#[cfg(not(debug_assertions))]
+let client = HttpClient::new(); // Uses OS trust store
+
+// ✅ GOOD: Development configuration  
+#[cfg(debug_assertions)]
 let client = HttpClient::builder()
-        .with_timeout(Duration::from_secs(10))
+    .insecure_accept_invalid_certs(true)  // Only in debug builds
     .build();
-}
 ```
 
-For development with self-signed certificates in browsers, you'll need to install certificates in the browser's certificate store rather than configuring them programmatically.
+## Examples
 
-### Environment Detection
+See the `examples/` directory for complete working examples:
 
-To handle both edge runtime and browser environments gracefully:
+- `examples/self-signed-certs/` - Comprehensive examples for all modes
+- Example of connecting to public endpoints (default mode)
+- Example of using custom Root CA for private services
+- Example of development mode with self-signed certificates
