Add automatic cleanup of old releases to save storage

- App releases: keeps latest 3 + v1.4.0 (last pre-Tauri version),
  deletes older releases and their tags
- Sidecar releases: keeps latest 2, deletes older releases and tags
  (sidecars are large, ~500MB-2GB each)

Cleanup runs after creating new releases, before triggering builds.
