- ReleaseChecker: mix a short hash of clusev.repository into the tag + changelog
cache keys so a cached value can never be reused across a host/repo change (the
promotion pipeline re-points CLUSEV_REPOSITORY between the private mirror and the
public repo).
- Strengthen the GitHub User-Agent test to assert the value (Clusev-Panel), not
mere presence — Guzzle always sets some UA, so the old check was a tautology.
