/**
 *
 * Producer-side CLI for the G1 fixture-replay anti-fake-green test
 * suite. Captures a real envelope artifact from
 * `.peaks/_runtime/<sid>/<role>/<envelope>` and writes a sanitized +
 * checksummed fixture pair (body + `fixture.meta.json`) into
 * `tests/fixtures/replay/`. Two sub-modes:
 *
 *   peaks fixture capture --from-rid <historical-rid> \
 *                        --sid <sid> --envelope <kind> \
 *                        --out tests/fixtures/replay
 *
 *   peaks fixture capture --variant-from <captured-fixture-path> \
 *                        --variant <edge-case> \
 *                        --out tests/fixtures/replay
 *
 * Why a CLI (not just a service function):
 *     every fixture under `tests/fixtures/replay/` MUST have a
 *     `producer: 'peaks-fixture-capture-cli'` in its `fixture.meta.json`
 *     and a `capturedAt` timestamp within a window where the CLI was
 *     invoked.
 *   - Dogfood: this CLI is itself used by the v2.14.0 release prep to
 *     rebuild the fixture set. Reviewers can replay the exact
 *     command from the meta to regenerate any fixture.
 *
 * File budget: ≤ 200 lines (Karpathy §2).
