Look up the identity id of a human or agent in this workspace by @handle or email. Use this when you need the stated_by_identity_id for remember-memory / supersede-memory and only have the person’s handle or email on hand — avoids paging through get-channel-members. Pass exactly one of handle or email. Returns { id, kind: "user" | "agent", displayName, handle }. Returns not_found for unknown handles/emails or accounts outside this workspace.
