The combined-image render (ROADMAP item 4, R1 shape confirmed by Andrey 07/19:
pose keeps its own 1/60 slot; depth-2 pipeline, +1 frame detection latency)
now runs from CuasPoseRT: after fitted[nscene] lands (fitted OR coasted -
every scene renders, the no-skip rule), the hook collects the previous
scene's render (normally already done - it ran during this scene's DP slot)
and enqueues this scene's full-frame chain NON-BLOCKING on the low-priority
render stream via GpuQuadJna.renderScene.

- CuasRtParameters: curt.det_render (default ON; JNA lean path only,
  fail-safe disables the stage for the run) + curt.det_render_save (DEBUG,
  TEST-ONLY blocking D2H per ruling 3.4 -> -CUAS-RT-DETINPUT stack).
- CuasPoseRT: per-sequence arm (renderSetup policy + FULL template = all
  tiles with valid disparity, the renderSceneVirtual selection=null
  convention + reference camera); per scene: render-private scene-camera
  snapshot (renderCameras - the pose loop's residents move on to N+1 before
  render(N) executes), shared uniform-MB descriptor (step 4 of
  poseMeasureSetup extracted verbatim into uniformMbDescriptor() - ops and
  order unchanged, both task streams carry the identical MB pair), ring-set
  captured before the D5 overlap flips it. NO per-scene prints - pose Done
  lines stay byte-identical; one-line stage summary after the loop.
- GpuQuad/GpuQuadJna/TpJna: renderSetup/renderTemplate/renderCameras/
  renderScene/renderStatus/renderGet (base = unsupported, JNA implements).

mvn package + test PASS. Native side: tile_processor_gpu d2e0395/59884af/
fe69ecc (render_dp chain, case render_pipe bit-exact, sanitizer 0,
run_cases ALL PASS, bench 4.30 ms/scene). Real-scene gate = R1c (Andrey's
routine run): Done-lines byte-identical vs the 07/16 22:52 record + 60/s
with the stage ON + -CUAS-RT-DETINPUT A/B vs CuasRender.
