gsxdsm 039d3ce440 FN-6236: move fast triage into workflow settings
Move fast triage prompting into the workflow/settings prompt model.

- Add a core-owned fast triage prompt and expose the workflow prompt mode type.
- Add a fast-mode builtin workflow variant and route triage prompt selection through workflow settings.
- Remove the engine-local fast triage prompt constant and update triage tests for workflow-driven fast mode.
- Document the fast triage prompt mode setting and add a patch changeset.
