- New source_candidates staging table (status suggested/quarantined/rejected/
promoted, preview_json snapshot) so untrusted/suggested feeds stay out of the
real ingestion path until reviewed.
- sources.py: save_candidate (re-preview never revives a curator's rejection),
list_candidates, reject_candidate, promote_candidate (copies into sources,
inactive by default — active on approval; never automatic).
- CLI: suggest-source / list-candidates / promote-candidate / reject-candidate.
- API: read-only GET /api/candidates (writes stay CLI-only — no unauthenticated
public write surface yet).
- Fix deprecated ElementTree truth-value test in _parse_rss.
- Tests: candidate lifecycle (save/list/promote/reject, status preservation,
name derivation) — 51 total.
