CLAUDE: strip TEMP migration probes + proactive side-effect-parity sweep

Migration validated (JNA CUAS targets match JCuda). Cleanup:
- Removed all TEMP debug probes (-Dtp.dbg.corrpair, probeClt, saveTDRender,
  the one-shot DBG/PROBE blocks in GpuQuadJna + CuasMotion). Real fixes kept
  (rectilinear port, num_pairs=3, setCorrIndicesTdData, imclt ref_scene,
  num_corr_tiles propagation f6dcc90f).
- Proactive sweep for the f6dcc90f bug-class (JNA override drops a base
  side-effect field write): getCorrComboIndices/getCorr2DCombo propagate
  num_corr_combo_tiles, setCorrIndicesTdData propagates num_corr_tiles,
  getTextureIndices propagates num_texture_tiles; those fields made protected.
  These four are LATENT (no live consumer on the validated CUAS path) and are
  marked NOT-YET-TESTED inline.

Java-only. mvn compile clean.
