/**
 * Commander stores a negated option such as `--no-history` as `history === false`; it never
 * sets `noHistory`. `chat --no-history`, `contexts export --no-secrets` and
 * `serve --no-recovery` read the `noX` name, so each flag was accepted and did nothing:
 * the prompt was still written to cli-history.jsonl, and the export still carried the
 * access tokens and API keys. These tests drive the real Commander parser instead of
 * hand-building an options object Commander never produces.
