/**
 * Correction Cue Learner
 *
 * Persistent, learnable keyword store for correction cue detection.
 * Replaces the hardcoded cue list in detectCorrectionCue() with a
 * crash-safe JSON store that can grow over time.
 *
 * Persistence contract:
 *   - Atomic write: temp-file-then-rename (T-38-02)
 *   - Cache invalidated after every write (D-05)
 *   - 200-term hard cap enforced before any write (T-38-01)
