feat: add production deployment support with broadcast functionality

[wukai9203]

Add comprehensive production deployment capabilities to foundry-huff library, enabling seamless transition from testing to real network deployment.

Core Changes:

• Refactor HuffConfig.sol deployment logic to support both test and production modes
• Move vm.prank(deployer) from creation_code() to deploy() function for better separation
• Add conditional deployment: vm.broadcast(deployer) for production, vm.prank(deployer) for testing
• Implement set_broadcast(true) method for enabling production deployment mode

Documentation Updates:

• Add complete "Production Deployment" section to README.md with practical examples
• Include deployment command: forge script scripts/Deploy.s.sol --rpc-url localhost:8545 --broadcast --private-key $SINGER_KEY
• Add contract verification example using cast call for RememberCreator contract
• Enhance all existing examples to demonstrate both test and production deployment modes
• Add security best practices, network configuration guides, and troubleshooting section
• Include production deployment checklist and private key management guidelines

Testing Enhancements:

• Extend test suite to cover both broadcast and prank deployment modes
• Add test cases for constructor caller verification with both deployment types
• Improve test code formatting and readability

Additional Files:

• Add scripts/Deploy.s.sol deployment script for production use
• Include deployment artifacts in broadcast/ directory

This update enables foundry-huff to be used in real-world production scenarios while maintaining full backward compatibility for testing environments.
