feat: diagnostic mode trasparente per find()
self._last_diag accumula counter durante find():
- Pipeline pruning: top_evaluated, top_passed, full_evaluated
- Candidati: n_raw, n_after_pre_nms, n_final
- Drop reason: ncc_low, min_score_post_avg, recall_low,
bbox_out_of_scene, nms_iou
- Param effettivi: top_thresh_used, verify_threshold_used, ecc.
API:
- find(debug=True): stampa one-line summary su stderr
- m.get_last_diag(): ritorna dict completo per inspection
Use case: 0 match? guarda dove sono finiti i candidati
(es. drop_ncc_low=200 → soglia NCC troppo alta) invece di
tirare a caso. Risolve il "find black-box" pattern.
