lmiranda 1e0d896d87 feat: implement MCP server core and authentication ...

Implemented MCP server core infrastructure with authentication and HTTP client:

- Created auth.py for API token management
  - Loads GITEA_API_URL and GITEA_API_TOKEN from environment
  - Uses python-dotenv for .env file support
  - Validates required configuration on initialization
  - Provides authentication headers for API requests

- Created client.py with base HTTP client
  - GiteaClient class using httpx AsyncClient
  - Async HTTP methods: get(), post(), patch(), delete()
  - Comprehensive error handling for HTTP status codes
  - Custom exception hierarchy for different error types
  - Configurable timeout (default 30s)

- Updated server.py with MCP server setup
  - Initialized MCP server with StdioServerTransport
  - Integrated AuthConfig and GiteaClient
  - Registered placeholder tool handlers (list_repositories, create_issue, create_pull_request)
  - Added CLI with --help and --version options
  - Proper error handling for configuration failures

- Updated pyproject.toml
  - Added console script entry point: gitea-mcp

- Created comprehensive unit tests
  - test_auth.py: Tests for AuthConfig validation and headers
  - test_client.py: Tests for GiteaClient initialization and error handling

All acceptance criteria met:
- MCP server initializes with StdioServerTransport
- Authentication loads from environment variables
- Base HTTP client with auth headers implemented
- Error handling for API connection failures
- Server reports available tools (placeholders for future issues)

Closes #2
