lib/nzb (buildNzb, parseNzb) from the current app; NzbService builds a release's NZB from its chunks; GET /api/v1/releases?q= (every word of the name) and GET /api/v1/releases/:id/nzb behind the api guard. A test stores a batch, finds the release and reads its NZB back. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
