Add ignore file pattern and enhance README

Updated the `.code-tokenizer-md-ignore` to include its own pattern for exclusion. Enhanced the README with a Quickstart section, detailed usage guidance, bundling process, and ignore file configuration.

+`## Ignore File Configuration`
+
+### .code-tokenizer-md-ignore
+
+The `.code-tokenizer-md-ignore` file allows you to specify patterns for files and directories that should be excluded from processing. You can create this file in any directory within your project, and it will affect that directory and all subdirectories.
+
+#### Features:
+
+- Supports nested ignore files (multiple .code-tokenizer-md-ignore files in different directories)
+- Uses glob patterns for matching
+- Inherits patterns from parent directories
+- Supports both relative and absolute paths
+
+Example `.code-tokenizer-md-ignore` file:
+```
+# Ignore specific files
+secrets.json
+config.private.ts
+
+# Ignore directories
+build/
+temp/
+
+# Glob patterns
+**/*.test.ts
+**/._*
+```
+
+#### Pattern Rules:
+- Lines starting with `#` are comments
+- Empty lines are ignored
+- Patterns are relative to the ignore file's location
+- Use `**` for matching across directories
+- Patterns without leading `/` or `**` are relative to the ignore file's directory
+- Patterns with leading `/` are relative to the project root

+## Bundling Process
+
+The project uses Bun's built-in bundler for creating optimized production builds. The bundling process includes:
+
+1. **Source Compilation**:
+    - TypeScript files are compiled using Bun's native TypeScript support
+    - Declaration files are generated using `bun-plugin-isolated-decl`
+    - Output is optimized for Node.js runtime
+
+2. **CLI Bundling**:
+    - Separate bundle for CLI usage
+    - Compiled to native binary for improved performance
+    - Includes shebang for direct execution
+
+3. **Output Structure**:
+   ```
+   dist/
+   ├── index.js      # Main library bundle
+   ├── index.d.ts    # TypeScript declarations
+   └── code-tokenizer-md  # CLI executable
+   ```
+
+4. **Bundle Configuration**:
+    - Target: Node.js
+    - Module Format: ESM
+    - Includes source maps
+    - Preserves path resolution
