Subject: [PATCH 01/11] Add BC PR-Review engine arm with BCQuality ref override

Lands the faithful convergence arm (engine adapter + BCQuality fetch/filter + review.json transform) and wires it into the CLI as 'bcbench evaluate engine'. The adapter accepts optional bcquality_repo/bcquality_ref that are passed to the engine's fetch via BCQUALITY_REPO/BCQUALITY_REF env vars, so a CI run can review against a modified BCQuality branch/SHA without editing the engine.

Subject: [PATCH 02/11] Wire engine arm into copilot-evaluation via committed
 BCQuality-ref toggle

Adds CODE_REVIEW_BCQUALITY_REF (default empty) to the existing 'Evaluation with GitHub Copilot' workflow. Empty keeps the current Copilot code-review; a branch that sets it runs the code-review through the BC PR-Review engine arm against that BCQuality ref. No new workflow or command surface for the user - flip one committed env on a branch.
