Add to the persistent TpProc API: tp_proc_setup_rbg_corr (imclt RBG + correlation buffers + corr
config), tp_proc_exec_imclt / tp_proc_get_rbg, tp_proc_exec_corr2d (correlate2D TD -> corr2D_combine
-> corr2D_normalize) / tp_proc_get_corr2d_combo. launch1() helper. tp_proc_convert_selftest extended
to validate imclt vs aux_chnN.rbg and quad corr vs aux_corr-quad.corr (order-independent, stale golden).

Validated on RTX 5060 Ti via the persistent API: CLT==golden (0.1085), RBG==golden (0.0201),
quad-corr value-err 2.06e-5, no_kernels runs finite. The persistent granular API now covers the
full set of GPU ops the LWIR16 CUAS workflow uses (geometry/convert_direct[+no_kernels/use_center_image/
erase_clt/ref_scene]/imclt/correlations) — the surface GpuQuadJna (integration step 2) delegates to.
