Fix CI release race: use gh CLI + || true for idempotent creates

- appimage.yaml: replace per-job softprops/action-gh-release with
  single release job using gh CLI (eliminates intra-workflow race)
- release-debs.yaml: replace softprops/action-gh-release with gh CLI,
  remove dead "Determine release tag" step and debugging noise
- Both workflows: add || true after gh release create to handle
  cross-workflow race (two workflows creating the same release)
