/**
 * Regression test for bug #2647 (also partial fix for #2649).
 *
 * v1.38.3 of get-shit-done-redux shipped with:
 *   - `files` array missing `sdk/dist`
 *   - `prepublishOnly` only running `build:hooks`, not `build:sdk`
 *
 * Result: the published tarball had no `sdk/dist/cli.js`. The `gsd-sdk`
 * bin shim in `bin/gsd-sdk.js` resolves `<pkg>/sdk/dist/cli.js`, which
 * didn't exist, so PATH fell through to the separately installed
 * `@opengsd/gsd-sdk@0.1.0` (predates the `query` subcommand).
 *
 * Every `gsd-sdk query <noun>` call in workflow docs thus failed on
 * fresh installs of 1.38.3.
 *
 * This test guards the OUTER package.json (get-shit-done-redux) so future
 * edits cannot silently drop either safeguard. A sibling test at
 * tests/bug-2519-sdk-tarball-dist.test.cjs guards the inner sdk package.
 *
 * The `npm pack` dry-run assertion makes the guard concrete: if the
 * files whitelist, the prepublishOnly chain, or the shim target ever
 * drift out of alignment, this fails.
