fix: install Alpine runtime dependencies (#434)

## Summary
- Install `libstdc++` and `libgcc` before verifying CLI versions from
apk archives
- Keep non-apk archive installs unchanged
- Rebuild the v1 bundled action artifact

## Testing
- `npm run package`
- `npm run format:check`
- `npm run lint`
- `npm run test`
- Verified `supabase_2.100.0_linux_arm64.apk` fails on plain Alpine
without `libstdc++`/`libgcc` and reports `2.100.0` after installing them
