feat: scaffold gitea-mcp package with module rename

- Copied source from leo-claude-mktplace/mcp-servers/gitea/ v1.0.0
- Renamed module: mcp_server → gitea_mcp (all imports updated)
- Created pyproject.toml for standalone package identity
- Preserved all existing tools and test suite
- MCP SDK imports unchanged
