* 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. Co-authored-by: Orca <help@stably.ai> * 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.
