* perf(native-chat): suspend hidden transcript streams
* fix(native-chat): keep assembly renders pure
* fix(native-chat): keep a transient error from stranding a revealed chat
- An error snapshot frame no longer latches frameArrived, so the in-flight
read can still seed the pane instead of leaving it on the error surface.
- Retained history is shown over a full-pane read error for the same source.
- The paged read window survives a hide/reveal; only a source change resets it.

* fix(mobile): match the trimmed native-chat retention signature
The shared retention type no longer takes `loading`, so mobile's call was an
excess-property error that broke the mobile typecheck job. Dropping it also
lets mobile inherit the desktop behavior: a stream error or dropped client
keeps the last transcript instead of swapping it for the error empty state.
