fix: add basic Wine support and test pipeline - #2001
Merged
Conversation
Make the Windows build compatible with Wine cross-compilation by using portable header casing, limiting MSVC-only abort setup, and accepting missing UBR registry metadata. Cross-compile Windows test binaries with Clang and MinGW-w64 on Ubuntu, then run the test suite through Wine. This exercises actual Windows code paths from Linux CI. Crashpad is skipped because its vendored Windows build does not currently cross-compile with this toolchain; other skips cover host-only harnesses or specific Wine limitations.

Consume the request body before returning a proxy authentication challenge so closing the connection does not produce a TCP reset. This lets Wine WinHTTP receive the challenge and retry with credentials.

This is a minimal preparation step for #1995 to make the tree Wine-compatible:
Cross-compile Windows test binaries with Clang and MinGW-w64 on Ubuntu, then run the test suite through Wine. This exercises actual Windows code paths from Linux CI. Crashpad is skipped because its vendored Windows build does not currently cross-compile with this toolchain; other skips cover host-only harnesses or specific Wine limitations.
