Detect videos with frozen frames (stuck picture while audio continues) using FFmpeg's freezedetect filter. Freeze events are marked as corruption with event count, total frozen time, and per-event timestamps. Configurable via FREEZE_DETECTION_ENABLED env var (default: true).
Added explicit Redis update after DB commit when transitioning to scanning phase, and a fallback to phase_total in the scan-status API when estimated_total is 0. Closes the gap where the UI showed stale progress data during chunk counting.
Chain blackdetect filter with freezedetect in a single FFmpeg decode pass. Freeze events that overlap with detected black sections (scene transitions, studio logos, end credits) are filtered out. Only freezes on actual video content are flagged as corruption.

Adjust freezedetect to n=-40dB:d=4 (stricter noise tolerance, 4s minimum duration) and blackdetect to d=1.0:pic_th=0.98 for better false positive filtering. Update README, CHANGELOG, and configuration docs with freeze detection details.
Tested against The Boondocks S01E06 (animation with held frames) which produced 22 false positives at d=4. At d=5, zero false positives while still catching real encoder freezes. Also changed freeze detection from corruption to warning-only.
…2.6.8) Two root causes: (1) _mark_scan_completed raw SQL UPDATE was overwritten by ORM identity map flush in _create_scan_report commit -- added expire_all after SQL commit. (2) Recovery endpoint and new scans did not clear stale Redis progress keys -- added clear_scan_progress_redis utility and calls at recovery and scan start.
