/**
 * Regression tests for bug #2136
 *
 * gsd-check-update-worker.js uses a MANAGED_HOOKS array (now in the shared
 * managed-hooks-registry.cjs module) to detect stale hooks after a GSD update.
 * It must list every hook file that GSD ships so that all deployed hooks are
 * checked for staleness — not just the .js ones.
 *
 * The original bug: the 3 bash hooks (gsd-phase-boundary.sh,
 * gsd-session-state.sh, gsd-validate-commit.sh) were missing from
 * MANAGED_HOOKS, so they would never be detected as stale after an update.
 *
 * Migration note (#455): previously used fs.readFileSync + regex on the worker
 * source to extract the array. Now requires the typed export directly from
 * hooks/managed-hooks-registry.cjs.
