Wires the semantic mapping into a callable scan pass:
- OscalControlsProvider: token-based fetch refactor + load_master_controls()
(pulls ?framework=master-controls)
- semantic_stamp_findings(): build the ControlIndex from the master-controls
catalog, then per finding embed its code region, retrieve the top-K nearest
master controls, grounded-judge confirm, and stamp the confirmed ids onto
control_refs (alongside the CRA CWE-LUT refs).
Opt-in — the orchestrator doesn't auto-run it, and it rebuilds the corpus index
per call (production should cache it). Live-verifiable once breakpilot #129 deploys.
