Stream advisor output into the advisor tool card while the nested
advisor call is still running.
This keeps the advisor implementation intentionally advisor-specific:
the parent model still receives the same final structured tool result,
while the frontend receives transient `tool-result.result_delta` parts
to render partial advisor text in the expanded card. The final persisted
chat history remains unchanged.

<summary>Implementation plan</summary>
- Publish advisor text deltas from the nested `chatloop.Run` via
`RunAdvisorOptions.OnAdviceDelta`.
- Forward those deltas through `chatadvisor.Tool` with the parent
advisor tool call ID.
- Emit transient `ChatMessagePartTypeToolResult` websocket parts with
`ResultDelta` from `chatd`.
- Add `result_delta` to the generated tool-result TypeScript variant.
- Accumulate tool result deltas in frontend stream state and keep the
tool running until the final result arrives.
- Render streamed advisor advice in the existing advisor card using
streaming markdown mode, while retaining the updated advisor UI.
