Merge upstream changes from main branch

This merge brings in new features and improvements from the main branch while
preserving Gitea-specific functionality:

- Updated README.md to maintain Gitea-specific setup instructions
- Preserved Gitea-specific authentication and API configurations
- Kept local git operations and MCP tool references for Gitea compatibility
- Removed GitHub-specific files (CONTRIBUTING.md, FAQ.md) and features
- Updated action.yml with new inputs while maintaining Gitea token usage
- Resolved conflicts in prompt generation to use Gitea comment tools

The merge maintains the Gitea fork's core functionality while incorporating
upstream bug fixes and feature enhancements.
