/**
 * User Suggestion Tracker
 *
 * Tracks user technical hypotheses and debugging suggestions so that:
 * - MetacognitiveVerifier can check if user hypothesis was tested
 * - BoundaryEnforcer can flag ignoring user expertise
 * - CrossReferenceValidator can match actions against suggestions
 *
 * Implements inst_049: "Test user hypothesis first"
 *
 * Usage:
 *   node scripts/track-user-suggestions.js --add "user hypothesis text"
 *   node scripts/track-user-suggestions.js --mark-tested "hypothesis id"
 *   node scripts/track-user-suggestions.js --check-untested
