Add gsio-client and gsio-wallet crates with initial implementations

- Introduced `gsio-client` crate for interacting with GSIO nodes, including ledger entry management and node discovery.
- Introduced `gsio-wallet` crate for key management, transaction creation, and wallet functionality.
- Updated workspace configuration to include new crates.

+### Using the Wallet
+
+The gsio-wallet library provides the following functions for managing wallets and transactions:
+
+- **Creating a new wallet**:
+  ```rust
+  use gsio_wallet::Wallet;
+
+  // Create a new empty wallet
+  let mut wallet = Wallet::new();
+
+  // Generate a new keypair and get the address
+  let address = wallet.generate_keypair().unwrap();
+  println!("New wallet address: {}", address);
+  ```
+
+- **Creating and signing a transaction**:
+  ```rust
+  use gsio_wallet::{Wallet, TransactionType};
+  use serde_json::json;
+
+  // Create a transaction
+  let mut transaction = wallet.create_transaction(
+      &sender_address,
+      &recipient_address,
+      100, // amount
+      10,  // fee
+      TransactionType::Transfer,
+      Some(json!({"memo": "Payment for services"}))
+  ).unwrap();
+
+  // Sign the transaction
+  wallet.sign_transaction(&mut transaction).unwrap();
+  ```
+
+- **Submitting a transaction**:
+  ```rust
+  // Submit the transaction to the network
+  let transaction_id = wallet.submit_transaction(&transaction).await.unwrap();
+  println!("Transaction submitted with ID: {}", transaction_id);
+  ```
+
+- **Checking account balance**:
+  ```rust
+  // Get account balance
+  let balance = wallet.get_balance(&address).unwrap();
+  println!("Account balance: {}", balance);

+
+The wallet system is implemented in `crates/gsio-wallet/src/lib.rs` and provides the following features:
+
+- **Key Management**: Generate and store cryptographic keypairs (using Ed25519)
+- **Account Management**: Create and manage accounts with addresses derived from public keys
+- **Transaction Creation**: Create various types of transactions (Transfer, Stake, Unstake)
+- **Transaction Signing**: Sign transactions with the account's private key
+- **Balance Tracking**: Track account balances and transaction history
+- **Secure Storage**: Save and load wallet data securely
