v0.2.0

skipbuild v0.2.0

Second release — focused on build-tool integration (response files, PCH), observability, and cleaner configuration naming.

⚠️ Breaking changes

• Environment variables renamed BUILDCACHE_* → SKIPBUILD_* (e.g. SKIPBUILD_DIR, SKIPBUILD_MAX_SIZE, SKIPBUILD_REMOTE_URL). The old BUILDCACHE_* names still work as a fallback, but SKIPBUILD_* takes precedence.
• Default paths renamed: cache dir ~/.cache/skipbuild (was .../buildcache), config .skipbuild.conf (was .buildcache.conf). Existing .buildcache.conf files are still read.

Added

• Response file (@file.rsp) support for compile commands (quoted/escaped args, CRLF, nested files).
• Precompiled header (PCH) support — MSVC (/Yc, /Yu, /Fp, /Y-) and GCC/Clang (-x c++-header, -include, -fpch-preprocess).
• REMAKE_LOG env var for log levels: debug, info, warn, error, none (legacy SKIPBUILD_DEBUG=1 still works).
• Visual Studio / MSBuild logging — [skipbuild] output goes via OutputDebugString, visible in VS Output → Debug.
• ARM64 CI: Ubuntu ARM64, macOS Apple Silicon, Windows ARM64.
• MSBuild incremental behavior: caching auto-disabled when the output is newer than the source.
• Remote caching guide (S3-compatible).

Changed

• Version centralized; skipbuild --version now reports 0.2.0 (no hardcoded versions).
• Response file parser hardened: strict bounds checks, max recursion depth (10), UTF-8 BOM stripping, CRLF normalization.
• Removed orphaned cache/remote.cpp (never compiled; duplicated core.cpp).
• Removed redundant release.yml; releases are built by build.yml.

Fixed

• Fatal 0xC0000409 (stack-buffer-overrun) crash parsing response files with quoted args on Windows.
• Quotes in response file tokens are now stripped (previously kept as part of the argument).
• Test-suite crashes during cleanup (stats tracker destructor ordering).
• Cache-key determinism across different build directories.
