Subject: [PATCH] chore(sw): bump cache version to v9 to purge stale HTML
 fragments

Stale cached HTML fragments referenced old asset hashes (e.g. 404 on
canvas-PlYnCtxh.js while server has canvas-R4rXE5Sc.js) after frequent
rebuilds. Bumping CACHE_VERSION and the SW registration query string
forces the new SW to install and purge all old versioned caches on
activate.
