/* kptv-2026-05-22: self-destruct service worker.
 *
 * Replaces the previous Workbox SW. Browsers visiting any admin2 URL will
 * fetch this file (browsers always re-check the SW), detect it's different
 * from the old SW, install + activate this one, which then:
 *   1. Wipes every cached entry (so the old bundles/index.html are dropped)
 *   2. Calls registration.unregister() so the SW won't intercept future visits
 *   3. Forces all open clients to reload so they pick up the fresh server copy
 *
 * Net effect: the admin2 admin panel is no longer a PWA -- every page load
 * fetches fresh from the network. Avoids endless cache invalidation pain.
