CLAUDE: GpuQuadJna getCltSize/getNumTiles/setCltData + native tp_proc_set_clt (CLT restore path)

convertCenterClt -> setComboToTD -> setCltData pushes the restored center CLT to GPU; base getCltSize/
getNumTiles deref null gpu_clt_wh. Override to full-frame dims; setCltData -> new tp_proc_set_clt
(HtoD per-cam slice, inverse of tp_proc_get_clt). Fixes the third JNA NPE (getCltSize:1211).
