+/**
+ * PreContextReset.hook.ts - Harvest session before /clear or /compact
+ *
+ * PURPOSE:
+ * /clear and /compact destroy conversation context without triggering SessionEnd.
+ * This means WorkCompletionLearning, RelationshipMemory, and progress snapshots
+ * are never captured. This hook intercepts those commands via UserPromptSubmit
+ * and runs a lightweight harvest before context is lost.
+ *
+ * TRIGGER: UserPromptSubmit
+ *
+ * INPUT:
+ * - stdin: Hook input JSON (session_id, prompt, transcript_path)
+ *
+ * FLOW:
+ * 1. Read prompt from stdin
+ * 2. If prompt is NOT /clear or /compact → exit immediately (<5ms)
+ * 3. If match → run harvest pipeline and exit
+ *
+ * SIDE EFFECTS:
+ * - Creates: MEMORY/LEARNING/<category>/<YYYY-MM>/<datetime>_context_reset.md
+ * - Appends: MEMORY/RELATIONSHIP/<YYYY-MM>/<YYYY-MM-DD>.md
+ * - Updates: MEMORY/STATE/progress/<project>-progress.json
+ * - Appends: MEMORY/LEARNING/SIGNALS/ratings.jsonl (reset marker)
+ *
+ * PERFORMANCE:
+ * - Non-matching prompts: <5ms (fast exit)
+ * - Matching prompts: <100ms (all disk I/O, no inference)
+ *
+ * INTER-HOOK RELATIONSHIPS:
+ * - RUNS BEFORE: Claude Code processes /clear or /compact
+ * - COORDINATES WITH: WorkCompletionLearning (SessionEnd) — same learning format
+ * - COORDINATES WITH: RelationshipMemory (SessionEnd) — same relationship format
+ * - DOES NOT run cleanup (session continues after /clear and /compact)
