FN-047: preserve project-scoped Chat context

Keep task Chat bound to the selected project even when its engine is unavailable.

- Resolve request-scoped TaskStore and ChatStore pairs without falling back to the default project.
- Apply the project-safe resolution to task planner and room chat routes.
- Add regression coverage and document the selected-project context guarantee.

## 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. 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.

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.
