fix(2136): add missing bash hooks to MANAGED_HOOKS staleness check (#2141)

* test(2136): add failing test for MANAGED_HOOKS missing bash hooks

Asserts that every gsd-*.js and gsd-*.sh file shipped in hooks/ appears
in the MANAGED_HOOKS array inside gsd-check-update.js. The three bash
hooks (gsd-phase-boundary.sh, gsd-session-state.sh, gsd-validate-commit.sh)
were absent, causing this test to fail before the fix.

* fix(2136): add gsd-phase-boundary.sh, gsd-session-state.sh, gsd-validate-commit.sh to MANAGED_HOOKS

The MANAGED_HOOKS array in gsd-check-update.js only listed the 6 JS hooks.
The 3 bash hooks were never checked for staleness after a GSD update, meaning
users could run stale shell hooks indefinitely without any warning.

+/**
+ * Regression tests for bug #2136
+ *
+ * gsd-check-update.js contains a MANAGED_HOOKS array used 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.
