feat: initialize Python project structure

- Create pyproject.toml with project metadata
- Add dependencies: mcp, httpx, python-dotenv
- Set up src/gitea_mcp package structure with __init__.py files
- Create placeholder server.py for MCP server implementation
- Add tools subdirectory for future tool implementations
- Create tests directory structure
- Update .gitignore with comprehensive Python exclusions
- Add README.md with project overview

Uses modern src-layout with pyproject.toml (no setup.py).
Project is ready for MCP server implementation.

Closes #1
