/**
 * test_squad_skill_design_llm.ts — Stories 8.1 + 8.2
 *
 * Asserts that:
 *   1. Brain.isAnyProviderAvailable() returns false when no env keys.
 *   2. SquadCreator.designWithBrain() falls back to heuristic when
 *      Brain reports no provider.
 *   3. With a mocked Brain that returns valid JSON, designWithBrain()
 *      returns source='brain'.
 *   4. With a mocked Brain that throws / returns junk, designWithBrain()
 *      gracefully falls back to source='heuristic'.
 *   5. Same four scenarios for SkillCreator.designWithBrain().
