OpenCode session timeline, loading, and reconnect behavior

Session title and inline rename live in message-timeline.tsx; scoped hooks use sync() and sdk(). Do not read an unused createResource in JSX: it triggers the nearest Suspense fallback even though its fetcher already runs reactively. persisted().ready is synchronous on web/localStorage but asynchronous on desktop storage; bootstrap API calls do not block GlobalSyncProvider. During reconnect and data catch-up, keep visible status in the timeline, home list, and sidebar. Deduplicate connection toasts with a shared Kobalte toast ID and reconnecting/catchingUp state. Archive/delete handlers optimistically remove sessions from sync().data.session, navigate away, and roll back failures with Binary.search; delete also removes descendants via byParent.
