feat: custom rpc for interacting with contracts

Add RPC URL Option to Contract Commands

Summary

This PR adds the ability to specify a custom RPC URL when using the deploy and call commands, allowing users to connect to different networks without modifying the codebase.

Changes

• Added a new --rpc option to both deploy and call commands in the CLI
• Extended the DeployOptions and CallOptions interfaces to include an optional rpc parameter
• Modified the getClient method call to accept the RPC URL parameter throughout the execution flow
• Added a new DeployScriptsOptions interface for improved type safety
• Updated the deployScripts method to accept and propagate the RPC URL to script executions
• Added comprehensive test coverage for the new functionality

Example Usage

# Deploy a contract using a custom RPC URL
genlayer deploy --contract myContract.gpy --rpc https://my-custom-rpc.com

# Call a contract method using a custom RPC URL
genlayer call 0x123456789 getData --rpc https://my-custom-rpc.com

# Deploy scripts using a custom RPC URL
genlayer deploy --rpc https://my-custom-rpc.com

Testing

Added unit tests for:

• Deploying contracts with a custom RPC URL
• Executing JS and TS deploy scripts with a custom RPC URL
• Calling contract read and write methods with a custom RPC URL

All tests are passing. The implementation maintains backward compatibility with existing code.
