* fix(#3329): reconcile stale managed .sh hook commands on install/update
applySettingsJsonHooks registers the four .sh managed hooks only-if-absent,
so entries registered before the #580/#3393 shellHookOmitsBashRunner fix kept
their bash-runner-prefixed commands forever — /gsd-update re-invokes the
installer but never re-derived existing entries. Add
reconcileManagedShellHookCommands (wired into applySettingsJsonHooks): on
win32+claude it rewrites existing managed .sh entries to the command this
install would generate today, scoped to exact managed basenames so
user-authored hooks are untouched, and inert wherever the bash runner is
still the correct shape.
Also bumps the allow-test-rule ceiling 301→302: PR #3455 added
tests/milestone-lock.test.cjs (the 302nd marked file) without the ratchet
bump, leaving lint-tests red on next.
