Automatic Vault recall

When attachments is omitted, Omni can recall relevant knowledge from the workspace automatically.

{
  "workspace_id": "workspace_...",
  "message": "What did our research say about the launch window?"
}

If ready Vault evidence supports the answer, the completed task contains validated [Vn] citations. Conversation context may appear as [Cn] citations.

Use explicit attachments only when the user has selected particular files.
