The IndexedDB cache, its crypto, the responder and the page-side sync go. lib/offline keeps its structure, policy, wipes, sign-out gates and notices; answers, the outbox and sync now live in lib/store, in a worker behind lib/store/client/api.ts. What users get besides that: - every folder is kept, not just the Inbox and opened ones - delete for good and empty trash work offline - a change the server refuses, or that meets a message changed on another device, is shown instead of dropped - a send whose response got lost is looked up by a Message-ID fixed when it was queued, then finished, submitted or sent again - with the store on, a start paints from the local copy, then connects An account the app drops by itself no longer wipes its data: only a sign-out or an explicit removal does. The outbox of the old database moves over once, in lib/offline/migrate-legacy.ts, and the old database goes only after the store committed. `isNetworkFailure` now counts timeouts and proxy 5xx. Sends and outbox requests are never answered from the device. Tests moved with the code: cache.test.ts and responder.test.ts are replaced by lib/store/__tests__/, and review-fixes.test.ts, outbox.test.ts and client-fallback.test.ts now run the real engine on node:sqlite. Changed assertions: an uncertain send is looked up rather than left alone forever, destroy and empty trash are queued rather than refused, and #9 (opened folders) became "a folder the server deleted goes", since all folders are kept.
