Rebuildable caches move from localStorage to IndexedDB (cache-store.js)

localStorage is ~5M characters per site whatever the device, and a phone
had filled it. Profiles, faceless list, reports, follow packs, profile
pages, relay lists, the moderation baseline, community directory, link
previews, video sizes/probes and search profiles (~3M on that phone) now
live in IndexedDB, which shares the site's disk allowance (GBs).

cacheStorage keeps localStorage's string API: reads from memory,
coalesced write-behind, flushed on hide. Copies migrate on open and are
removed once written. Boot waits for it (max 3s) beside the Ark store;
caches read at construction re-merge on ready; an early write can't
replace the stored copy. A copy an older build writes to localStorage
later moves in on first ask. Wallet wipes reach it; private mode stays on
localStorage. Read markers, drafts, follows, note threads and sync
outboxes stay in localStorage on purpose (cross-tab consistency, early
server-rendered seeding). Also asks navigator.storage.persist().
