The bundled hooks README listed only command/agent/gateway events and
ended with a stale "More event types coming soon (session lifecycle,
agent errors, etc.)" line, but production code now triggers:
- session:compact:before / session:compact:after via
src/agents/pi-embedded-runner/compaction-hooks.ts
- message:received via src/auto-reply/reply/dispatch-from-config.ts
- message:sent via src/infra/outbound/deliver.ts
Updates the "Event Types" list with the four real production event
names, drops the stale coming-soon line, and aligns the InternalHookEvent
interface example with the actual InternalHookEventType union (adds
"message" and refreshes the action examples). HOOK.md authors that target
session lifecycle or message routing now have a real surface to subscribe
to instead of relying on tribal knowledge or the type definitions.
