FN-099: match task Chat model menu width to Direct Chat

Match the task Chat model selector to Direct Chat sizing so provider and model names remain readable across desktop and mobile.

- Apply the shared readable, viewport-clamped dropdown width to Task Chat.
- Add regression coverage and desktop/mobile screenshots.
- Document the behavior and publish a patch changeset.

## Task-detail Chat
Task-detail **Chat** uses the project’s configured Direct Chat default model and thinking level rather than the task’s planning model. It remains task-aware: the server builds the task definition, dependencies, activity, metrics, steering, and refinement context, and the existing `task-planner:<taskId>` session keeps one transcript per task. Task context always comes from the selected project’s authoritative store, including while that project’s engine has not started or is unavailable; another project’s task with the same ID cannot supply its context. The composer exposes the same model and thinking controls as Direct Chat; model choices remain model-targeted and do not replace the synthetic task-scoped permission contract. Changing the project default does not hide history, and the next explicit send applies the current target to the existing idle session. There is no separate planner-model lane for this conversation.
