fix(sw): stop unbounded cache growth — delete stale caches on activate, cache only static assets 

- activate: delete ALL caches except current STATIC/RUNTIME (was keeping every
  previous construction-delivery-* cache forever → 3GB storage, 30-40s caches.match)
- fetch: only cache same-origin static assets (js/css/img/fonts); API/data and
  cross-origin requests go straight to network, never cached
- bump to v115
