📝 Full Task Prompt

Objective: Add regression tests for immediate-send rich widget suggestions.

Scope:
- Cover suggestion click and keyboard activation in the widget renderer.
- Verify the new direct-send path does not regress other widget actions.

Requirements:
- Suggestions send immediately.
- Suggestions do not populate the chat input first.
- The supported widget surfaces all share the same behavior.

Constraints:
- Keep tests deterministic.
- Avoid brittle DOM timing assumptions.

Verification:
- Dashboard tests cover the new interaction path.
- Build still succeeds after the changes.
