 * Regression test for bug #3019.
 *
 * `gsd-sdk query <subcommand> --help` returned the top-level SDK USAGE
 * instead of contextual help for the subcommand. The query argv parser
 * harvested --help as a global flag and main() short-circuited dispatch
 * before the registry handler / gsd-tools.cjs fallback could render
 * useful help.
 *
 * Two-layer fix:
 *   1. sdk/src/cli.ts  — leave --help in queryArgv so it travels to the
 *      handler/fallback. Only honor the global help flag when there is
 *      no subcommand to dispatch to.
 *   2. gsd-core/bin/gsd-tools.cjs — render the top-level usage on
 *      --help instead of erroring. Anti-hallucination invariant from
 *      #1818 is preserved (the destructive command never executes).
 *
 * Tests the integration: invoke gsd-tools.cjs the same way the SDK
 * dispatcher does and assert structured-IR (success flag + usage shape)
 * rather than raw substring matches.
