* fix(native-chat): stop rendering tool output as the agent's streaming reply
A tool result could appear in native chat as a raw, un-collapsed "assistant"
bubble that never went away for the rest of the turn — on mobile it showed up
as a wall of a source file's contents, prefixed by "Exit code 1".
Providers publish a tool's stdout/error as `lastAssistantMessage` so status
cards and dashboard rows can preview what the agent just did. Native chat reuses
that same field as its live streaming bubble, so the preview rendered as prose.
For Claude the preview is *only ever* tool output mid-turn: claude-tool-fields
writes real prose exclusively at Stop, so the bubble could never contain an
actual streaming reply.
It also could not be retired. The bubble hides once a transcript assistant block
leads with the streamed text, and tool output never lands in one — so the only
remaining exit was the turn ending, which is why a long tool-heavy turn pinned it
on screen.
Carry provenance instead of changing what the status surfaces show: mark the
writes that come from a tool result/error, keep the flag in lockstep with the
value it describes through the listener merge, and have both native-chat
streaming paths ignore a flagged preview. Status cards, dashboard rows and
automation capture are untouched.
The wire field is optional, so an older host that never sends it keeps today's
behavior rather than silently suppressing previews.
* fix(native-chat): preserve tool output provenance through renderer sync
* fix(native-chat): retain preview provenance in Claude roster state
* test(native-chat): cover restored tool preview provenance
