* Revert "Restore cached conversations before reconnecting (#4421)"
This reverts commit 1c51b52d07.
* fix(app): restore provider loading on native
* fix(app): preserve native navigators across appearance changes
Reapply the isolated appearance boundaries and native menu transform origin from #4421 so appearance hydration preserves native navigator and gesture host lifetimes.
* fix(app): retain cached baselines during live updates
Read the timeline concurrently with agent preparation and reconcile display-only cache rows beneath the live head using the existing reducer. Merge cached directory entries beneath live state while preserving the existing checkpoint race guard.
