ci: release.yml nur noch Docker-Build (Release macht release.sh)

- "Create Gitea Release"-Step entfernt → keine doppelte Release-Erstellung
  mehr (release.sh legt Release + englischen Auto-Changelog + Assets an).
- Image-Tag strippt fuehrendes 'v' (VERSION-Datei hat keins).
- Tag-Pattern auf 'v*' erweitert (vorher matchte v0.9.x.y-Hotfixes nicht).
