fix: publish desktop-specific frontend release artifact (#9206)

## Summary
- add a desktop-specific frontend release artifact (`dist-desktop.zip`)
in release draft creation
- build `dist-desktop.zip` with `DISTRIBUTION=desktop`
- keep existing `dist.zip` behavior for core/PyPI consumers
- extend `scripts/zipdist.js` to support custom source and output paths
