merge: pull upstream/main (2.7.4) into feature/best-quality-search-mode
- Keep our v3 ranked-targets quality system (filter_and_rank, QualityTarget)
in soulseek_client.py, settings.js, database presets, and index.html
- Take upstream removal of standalone quality-scanner code:
QualityScannerDeps + run_quality_scanner moved to repair job
(core/repair_jobs/quality_upgrade_scanner.py)
- Take upstream AAC-tier addition in database/music_database.py default profile
- Take upstream removal of /api/quality-scanner/* routes from web_server.py
- Remove test_discovery_quality_scanner.py (deleted upstream)
- 47 upstream commits absorbed (2.7.3 + 2.7.4 including re-identify flow,
dead-folder cleanup, track-number prefix strip, and more)
