/**
 * Detects `mjst version` / `mjst help` and the `--version` / `-v` / `--help` /
 * `-h` flags in raw argv.
 *
 * The subtlety is *where* the token sits. Scanning the whole argv with
 * `includes('-v')` meant that any flag whose **value** happened to be `-v` — say
 * `--type-suffix -v` — printed the version and exited 0 without generating
 * anything, which CI reads as a successful build. So a token in the value
 * position of a value-taking flag is skipped: it belongs to that flag.
 *
 * @returns What the args ask for, or `undefined` for a normal generation run.
