byrongamatosandClaude Sonnet 4.6 cafb1ee790 fix(scan): mass-prune guard v2 — partial degraded listing refused on auto scan ...

The v1 zero-listing guard (f6e9727) was bypassed by a partial degraded
mount: if even one song was visible, current_files was non-empty and
delete_missing ran freely, pruning every invisible DB row (Creed r1 HIGH).

Guard contract (god ruling):
- Auto scans (startup, periodic, /api/rescan): refuse when
  would_remove >= max(_PRUNE_MAX_ABS=1, _PRUNE_MAX_FRAC=0.5 * existing).
  Zero-listing also refused (would_remove == existing).
  Scan sets stage='error', leaves DB intact.
- /api/rescan/full: allow_mass_prune=True → guard logs a warning and
  proceeds; delete_missing runs (user-authorised explicit intent).

Changes:
- lib/scan.py: _PRUNE_MAX_ABS/FRAC constants; combined guard (zero +
  partial) before delete_missing; allow_mass_prune param on
  background_scan(); _scan_mass_prune_next global threaded through
  kick_scan() and _scan_runner()
- server.py: trigger_full_rescan calls kick_scan(allow_mass_prune=True)
- tests/test_scan_prune_guard.py: Case B (Creed partial, RED f6e9727→
  GREEN here) + Case C (full-rescan bypass)
