fix: improve Rust component integration and update documentation

Enhance Rust WebAssembly component support with better integration
patterns and update project documentation for production use.

Rust improvements:
- Better component model integration with wit-bindgen
- Enhanced build configuration for optimized WebAssembly output
- Improved error handling for component generation failures
- Support for both wasip1 and wasip2 targets with proper configuration

Documentation updates:
- Updated README with comprehensive usage examples
- Added multi-language development workflow documentation
- Included production deployment best practices
- Added troubleshooting section for common build issues
- Enhanced getting started guide with step-by-step instructions

Build system enhancements:
- Improved caching behavior for faster incremental builds
- Better integration between Rust rules and component toolchain
- Enhanced validation for component interface compatibility
- Support for complex component composition scenarios

These changes complete the foundation for a production-ready
WebAssembly component development environment with proper
multi-language support and comprehensive documentation.
