gsxdsm 42bbe58c03 FN-7579: add ask-user and exit-gate workflow nodes ...

Add workflow nodes for mid-flow user reach-out and early exit from a workflow run.

- Add `ask-user` IR node kind that reuses the await-input park/resume mechanism and surfaces the question in the task chat for brainstorming/clarification.
- Add `exit-gate` IR node kind that terminates the workflow early, with an optional condition.
- Wire both node kinds through the engine executor and workflow-node-handlers, including a new exit-gate-runner.
- Update the WorkflowNodeEditor palette, node summaries, and node help text for the two new node types.
- Extend workflow-flow-mapping to support the new node kinds.
- Keep `prompt`+`awaitInput` as a back-compat alias.
- Add core/engine/dashboard tests covering the new node kinds.
- Document the new nodes in docs/workflow-steps.md.
- Add changeset for the new minor feature.
