feat: add macOS platform support, GPG-signed release workflow

- Native macOS fingerprint config (platform=macos, skip GPU/concurrency spoofing)
- Enable darwin-arm64 and darwin-x64 in AVAILABLE_PLATFORMS (Python + JS)
- Update release workflow: multi-platform title, patch count, GPG key reference
- Update platform tables in both READMEs: macOS Intel now available
- Fix stealth test timeouts
