/**
 * [WHO]: Provides IdleThink state, budget checks, lifecycle cleanup, and exploration loop orchestration
 * [FROM]: Depends on core extension context types, ./thinker, ./insights, and ./curiosity for exploration side effects
 * [TO]: Consumed by ./index.ts and idle-think behavior tests
 * [HERE]: extensions/builtin/idle-think/idle-think-runtime.ts - testable runtime boundary for idle exploration
