fix(rules): add architecture and version checks to library rule matching

Complete the rule_matches function to properly evaluate:
- OS name (already working: osx/macos, linux, windows)
- Architecture (arch field): match against env::consts::ARCH
- OS version (version field): accept all versions for now (conservative)

This ensures that architecture-specific libraries (e.g. natives-arm64)
are correctly filtered based on the current platform.
