/**
 * `slowcook brew --pair-sim` — local-only pair-brew simulator.
 *
 * Self-contained orchestration of driver + navigator agents using the
 * Anthropic API directly. Skips the production brew agent's tool-use
 * loop in favour of a "driver returns JSON describing files to write"
 * shape — much simpler to wire than the full tool protocol, and good
 * enough to validate the pair dynamics empirically.
 *
 * Per iteration:
 *   1. DRIVER reads spec + tests + mock + history → returns JSON
 *      { rationale, files: [{path, content}], halt? }.
 *   2. Apply files to disk; compute git diff.
 *   3. NAVIGATOR reads diff + mock + code-map digest + tests + history
 *      → returns NavigatorVerdict JSON.
 *   4. If verdict.overall === "block": revert files, fold concerns into
 *      next iter's history, continue.
 *   5. Else: run vitest on the story tests. If green + no cross-story
 *      regression: SUCCESS. If story tests fail: history.failures →
 *      next iter. If cross-story regression: revert + log.
 *   6. Halt at max-iters.
 *
 * Output: per-iter transcript to stdout; final summary written to
 * .brewing/pair-sim/<story-id>-<timestamp>.json.
 *
 * Requires: ANTHROPIC_API_KEY in env. Run from the consumer's repo root.
