🎉 feat(ci): aggiungi versionamento semantico per shared-actions

- Aggiunto package.json con versione 1.0.0
- Nuovo workflow release.yml standalone: crea release Gitea su tag v*
- Aggiornamento automatico tag major floating (v1 → latest v1.x.x)
- Esempi aggiornati da @main a @v1 (tag major stabile)

Flusso di release:
  git tag v1.0.0 && git push origin v1.0.0
  → crea release Gitea con changelog
  → aggiorna tag floating v1
