/**
 * 0.19.0-α.13 — single env-var knob for "don't write to the
 * consumer's GitHub repo." Used when a slowcook maintainer (or
 * anyone debugging) replays a slowcook command on someone else's
 * repo — clones, checks out, runs the LLM, gets a verdict, but
 * never commits / pushes / comments / labels / closes.
 *
 * This complements per-command `--dry-run` flags. A command's
 * `--dry-run` typically gates SOME local writes (e.g., persisting
 * a verdict file in `.brewing/`); SLOWCOOK_READ_ONLY gates remote
 * writes specifically. Both can be set together.
 *
 * Pure: just inspects process.env. Tested in isolation.
