models/, .venv/, *.joblib, and *.pt.

Root cause of poor discrimination: MFCC[0] (energy) dominated the
feature vector, making cosine similarity see all audio as similar.
Changes:
- Skip MFCC[0], use 12 coefficients instead of 20
- Add delta MFCCs for temporal dynamics
- Add 7-band spectral contrast for tonal vs noise quality
- Switch from cosine similarity to euclidean-distance-based score
- Pre-compute STFT once for whole file (10-20x faster)
- Vectorized sliding window via cumulative sums (no Python loop)
- Lower sample rate 22050→16000 Hz (faster, no quality loss)
- 62-dim feature vector (was 40-dim mean+std of raw MFCCs)
- Default threshold 0.05 (new similarity scale)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Mean-only vectors were too similar across different audio segments,
causing everything to match even at threshold 0.99. Adding std
captures temporal dynamics and makes the similarity scores much
more spread out.

1. Rename ScanWorker.finished → scan_done to stop shadowing
QThread.finished. Previously, cancelled scans leaked the QThread
because the custom signal was never emitted.
2. Block signals on combobox reset in _on_scan_ref_changed to
prevent re-entrant call when user cancels folder dialog.
3. Merge overlapping scan regions into clusters before S-key
navigation so it jumps to the next distinct match, not 1s forward
through overlapping windows.

When cancelling a scan during file change, connect finished signal

- Autoclip (A): adjusts clip count to fit current pause position
- Pause no longer resets playback position — stays where paused
- Play resumes from pause point instead of restarting
- Spread/clips changes update loop end without restarting playback

- Lock mode: ignore stale mpv position updates while user is dragging
to prevent the play position from jumping back.
