/**
 * Live probe — primitive #2 (runCritiquePass) verification.
 *
 * Runs reflexion + plan-execute-reflect against Ollama on a task that
 * naturally invokes the critique pass (multi-pass, evaluation-driven).
 *
 * Asserts both strategies:
 *   - Complete without crash
 *   - Emit at least one critique/reflection step (proves the shared primitive
 *     was actually invoked)
 *   - Produce non-empty output (proves the thinking-safe extraction in the
 *     primitive successfully delivered usable critique text to the
 *     satisfaction / refinement logic)
 *
 * Run:  bun apps/examples/src/reasoning/critique-probe.ts
