feat: Implement provider loader dynamic imports with GitHub URL support

- Add URL detection and parsing utilities for GitHub URLs, local paths, and NPM packages
- Implement git operations for cloning and updating repositories with local caching
- Add automatic update checking mechanism for GitHub repositories
- Update provider-loader.ts to support multiple source types with comprehensive error handling
- Add comprehensive test coverage for all new functionality
- Include complete documentation with usage examples
- Support GitHub URLs: https://github.com/user/repo, user/repo@branch
- Support local paths: ./path, /absolute/path
- Support NPM packages: package-name, @scope/package
- Maintain backward compatibility with existing providers
- Add fallback mechanisms and interface validation
