CLAUDE: v2 Stage-2 Hough-vote wiring + curt_c5_en flag + ORT log fix

- CuasStage2Infer: ONNX runner for the learned Stage-2 vote-refine (full-field conv).
- CuasDetectRT: voteScatter (s^2-weighted bilinear splat at tail T=P-V*(N-1)) + reg-branch
  wiring -> saves -VOTE heatmap + -REFINED detection when curt_stage2_model is set;
  curt_c5_en gates the heavy C5P convolve (DNN-only fast path).
- IntersceneMatchParameters: curt_c5_en + curt_stage2_model params (all 6 sites each).
- CuasDnnInfer: setSessionLogLevel(ERROR) to suppress benign ORT VerifyOutputSizes warnings.
