feat: implement Gitea MCP Server with full test coverage

Phase 1 implementation complete:
- Complete MCP server with 8 tools (list_issues, get_issue, create_issue, update_issue, add_comment, get_labels, suggest_labels, aggregate_issues)
- Hybrid configuration system (system-level + project-level)
- Branch-aware security model (main/staging/development)
- Mode detection (project vs company/PMO)
- Intelligent label suggestion (44-label taxonomy)
- 42 unit tests (100% passing)
- Comprehensive documentation (README.md, TESTING.md)

Files implemented:
- mcp_server/config.py - Configuration loader
- mcp_server/gitea_client.py - Gitea API client
- mcp_server/server.py - MCP server entry point
- mcp_server/tools/issues.py - Issue operations
- mcp_server/tools/labels.py - Label management
- tests/ - Complete test suite (42 tests)
