/**
 * `slowcook eval` — 0.19.0-α.17 (closes #19, partial).
 *
 * No-regression gate for prompt-changing PRs. Loads frozen fixtures
 * from `packages/cli/eval/fixtures/<id>/fixture.json`, calls the
 * relevant `build*Prompt(args)` function from `@slowcook-ai/llm-anthropic`,
 * and asserts the resulting prompt string contains all of the
 * fixture's `expected_prompt_includes` substrings and none of its
 * `expected_prompt_excludes` substrings.
 *
 * Why prompt-shape assertions instead of running the LLM against the
 * fixture: the regression class #19 names ("subtle prompt drift that
 * drops critical context") is structural. Asserting on construction
 * shape catches it deterministically without burning Anthropic credit
 * or introducing nondeterminism into CI. A future fixture-class can
 * layer LLM-output assertions on top once we have a recorded-replay
 * shape; today this gate is the cheap, fast, contract-grade floor.
 *
 * Discovery model: walks `packages/cli/eval/fixtures/<id>/` directly
 * by listing subdirectories with a `fixture.json` inside. No central
 * registry — each fixture is self-describing.
