* feat(sync): restore host directories before reconnect
Persist complete project, workspace, and active-agent replicas so every registered host can paint immediately, including offline hosts. Reconcile those replicas through monotonic per-entity cursors on the existing directory RPCs without retaining an event journal.
* fix(sync): preserve active turn identity during catch-up
Own Agent-to-wire projection beside the existing snapshot normalizer so replica persistence does not reach through directory-sync internals. This also keeps identified active turns intact when unchanged agents are folded into an incremental directory response.
* test(e2e): inspect the real IndexedDB replica
Keep cache setup, reload, and hydration coverage on the production browser storage backend after the replica moved off localStorage. Measure writes at the actual IndexedDB put boundary as well.
* fix warm reconnect cache paths
* feat(sync): persist project icons and deepen directory sync
* fix(sync): preserve project update order
* fix(cache): preserve validated replica persistence
* fix(sync): retain cached agents during catch-up
* perf(app): skip transient replica cache writes
The replica cache subscribed to the entire session store, so live stream-head updates forced repeated JSON serialization and browser storage writes even though the head is not persisted. Select the cache's persisted inputs once and schedule writes only when that projection changes.
* test(app): move perf cleanup into fixture
Keep the replica-cache performance scenario as a direct setup, stream, measure, and assert flow while the spec-local Playwright fixture owns deterministic mock-agent cleanup.
