Fuzz-match scorer registry shared between SupplierBase.fuzzyFilter and the Advanced drawer section's override selector. Keys are stored in userSettings.fuzzScorerOverride; when present at search time they replace each supplier's per-class fuzzScorer default.

distance is intentionally excluded — it's an edit distance (lower = more similar), while all other scorers return 0–100 (higher = more similar), so it doesn't plug into the same cutoff/filter flow.
