04-02: Added SessionStart hook wiring verification to Task 3 and
key_links. The hook already exists from Phase 2 - plan now verifies
it correctly injects the new graph-backed summary format.
04-03: Removed embedded JavaScript execution pattern. Commands are
instructions Claude follows, not scripts. Entity generation now uses
Task tool to spawn subagents for batch processing instead of pretending
markdown can execute JS.
