tiennm99 713eb5bbde ci: bump actions to latest, pin windows runner ...

- actions/checkout v4 -> v6 (Node 24, addresses Node 20 deprecation).
- runs-on windows-latest -> windows-2025 (current image; pin avoids
  silent surprise when GitHub redirects windows-latest to a newer
  image mid-2026).
- Swatinem/rust-cache@v2 retained (v2 floating tag still maintained;
  latest is v2.9.1 under that major).
