Workflow C: Implement Epilogue interaction with engineering intent

This workflow connects product-level interactions to engineering work. It begins with an interaction from the Epilogue Tracker, compiles a formation brief and prompt packs, runs through Foundry, and ingests the result as trace feedback.

1. User selects an Epilogue interaction.
2. Alloy retrieves related engineering intent.
3. Alloy asks for clarification if needed.
4. Alloy creates a formation brief.
5. Alloy compiles prompt packs and evidence plan.
6. Foundry runs dry-run first, then full if permitted.
7. Foundry executes the selected formation.
8. Alloy ingests the trace.
9. Alloy updates evidence and reports intent satisfaction.
