ci: fix test_subagent strcasestr crash; llvm-mingw Windows zip

clang under strict C11 left strcasestr undeclared (returns int → pointer truncation → SIGSEGV). Parse Content-Length portably; keep -Werror on make check. Drop Nix for windows-cross (root /nix fails) and use pinned llvm-mingw UCRT instead; Alpine musl gets linux-headers for audit.h.
