Advanced Service Worker lifecycle management and update control

Advanced lifecycle management ensures controlled updates, avoids cache conflicts, and guarantees consistent app behavior across versions.

In production PWAs, Service Worker lifecycle management is critical because multiple versions of SW can coexist. Developers must handle install, waiting, and activate states carefully. Techniques like skipWaiting() and clients.claim() allow controlled activation. Proper versioning ensures old caches are cleaned and users don't experience mixed asset states.
