Added

• DXT Extension Support: Complete restructuring to support Anthropic DXT (Desktop Extensions) packaging format
• DXT-compliant directory structure with server/ containing bundled dependencies and entry point
• New server/main.py entry point following official DXT conventions
• Automated DXT package building via GitHub Actions workflow (.github/workflows/dxt-release.yml)
• Bundled dependencies in server/lib/ directory for self-contained extension deployment
• Updated manifest.json with proper DXT configuration and PYTHONPATH setup
• DXT installation instructions as primary recommended installation method in README
• Automated release workflow that builds both Docker images and DXT packages
• DXT package validation and testing scripts

Changed

• Project Structure: Restructured from src/ layout to DXT-compliant server/ layout
• Installation Priority: DXT extension is now the primary recommended installation method
• README.md: Completely reorganized to prioritize DXT installation while preserving all existing content
• Dependency Management: Moved from runtime dependency installation to bundled dependencies approach
• Entry Point: Changed from python -m propublica_mcp.server to python server/main.py
• PYTHONPATH Configuration: Updated to use ${__dirname}/server/lib:${__dirname}/server for DXT compatibility

Fixed

• Module resolution issues when running as DXT extension by implementing proper sys.path setup
• Virtual environment compatibility by bundling all dependencies in extension package
• Runtime dependency conflicts by using vendored dependencies approach

Technical Details

• Maintains full backward compatibility with existing Docker and Python installation methods
• Supports hybrid deployment strategy (DXT for local, Docker for production)
• Automatic GitHub release creation with both Docker images and DXT packages
• Enhanced CI/CD pipeline for multi-format package distribution
