Windows runners need cache archives to use the system tar without a POSIX shell and to keep restore confinement correct for drive-qualified paths.

Fixes #5

What changed

  • Switched archive create, list, and extract to direct tar invocations instead of bash pipelines.
  • Added Windows-aware restore confinement for drive paths, backslash traversal, drive-relative entries, and link targets.
  • Added bsdtar listing parsing and cache-version coverage for Linux versus Windows when cross-OS archives are disabled.
  • Updated README, MIGRATION, and SECURITY docs for Windows runner behavior and cross-OS limits.

Testing

  • focused Windows path and archive tests
  • npm test
  • npm run check
