Why: Establish one validated project-local routing document before any real Agent execution is enabled.
Evidence: Cursor observed red then 12 green configuration tests; the host replays those tests, the temporary validation target, and whitespace checks during integration.
Impact: Adds the U1 configuration contract and parser only; real routing, adapters, controller execution, and governance adoption remain disabled.
