Fusion Agent 0899d49e5c FN-016: preserve interrupted chat responses

Persist partial assistant output when chat streaming is stopped so users can resume from an honest interrupted transcript.

- Snapshot streamed text, thinking, and tool calls before cancellation.
- Persist and reconcile interrupted responses for main chat and planner chat surfaces.
- Add cancellation routes, manager handling, changeset metadata, and desktop/mobile regression coverage.
