/**
 * Synthetic-workspace scenario runner for skill-behavior tests.
 *
 * Each scenario:
 *   1. Creates a temp workspace.
 *   2. Builds a neutral .claude/skills/impeccable into the workspace so
 *      the launcher (`scripts/impeccable`) resolves from the canonical path
 *      the skill references, and points it at an engine binary.
 *   3. Optionally writes PRODUCT.md / DESIGN.md fixtures.
 *   4. Inlines SKILL.md as the system prompt (placeholders stripped to
 *      neutral values so the same body works for all providers).
 *   5. Runs Vercel AI SDK generateText with workspace-scoped tools
 *      (bash, read, write, list, ask_user_question).
 *   6. Captures every tool call and returns a trace + the raw response
 *      messages (so multi-turn scenarios can append to them).
 *
 * The harness deliberately mirrors the live-mode E2E pattern: real LLM,
 * no mocked model. File tools are workspace-scoped; bash is a real host shell,
 * not a security sandbox. Run only against disposable synthetic fixtures.
