Since #22401 every socks* PROXY_URI is handed to undici's ProxyAgent,
which only accepts socks5: and socks:. A socks5h, socks4 or socks4a
URI fell through to its HTTP proxy path and threw "Invalid URL
protocol" while the proxy module loaded, so the server never started,
even though unify-proxy listed all of them as supported.
Pass socks5h to undici as socks5: its SOCKS5 client sends host names
to the proxy, so DNS still resolves there, as playwright.ts already
assumes. undici has no SOCKS4 support, so drop socks4 and socks4a from
the accepted protocols, which logs the supported list and disables the
proxy like any other unsupported protocol.
* feat(tests): add comprehensive unit tests for various utility functions and views
- Implement tests for cache utility to ensure proper behavior with no cache and TTL keys.
- Add tests for common utilities including string manipulation and path handling.
- Introduce tests for directory import functionality to validate file imports and pattern matching.
- Create tests for git hash retrieval to handle fallback scenarios.
- Develop tests for deprecated got utility to verify response handling and retry logic.
- Enhance got utility tests to include request hooks and search parameter handling.
- Mock header generator tests to validate user agent handling.
- Expand helpers tests to cover current path retrieval and duration parsing.
- Implement tests for ofetch utility to ensure proper proxy handling and logging.
- Add OpenTelemetry metric tests to validate metric serialization.
- Create proxy tests to verify multi-proxy selection and failure handling.
- Introduce request rewriter tests to validate fetch and get wrapper functionality.
- Add timezone utility tests to handle various input types.
- Implement view tests for Atom and RSS rendering to ensure correct output.
- Create index view tests to validate debug information display based on configuration.
* refactor: remove deprecated got implementation and associated tests
* test: expand coverage for api, middleware, and utils
