Union.Manifold v3.6.9

Fixed

• Release pipeline, follow-up to 3.6.8: pre-creating the draft release was
  not enough. tauri-action looks drafts up by tag, but a draft's git tag
  does not exist until publish, so each platform job still created its own
  draft and 3.6.8 published with only the Linux packages. Every platform
  job now receives the draft's numeric release id and uploads directly to
  it, so Windows, AppImage, deb, RPM, pacman, and both macOS builds land in
  the one published release.
