CLAUDE: Stage 5 — native textures_nonoverlap via JNA (executes on Blackwell; golden mismatch documented)

Extend run_convert_pipeline with do_tex: setTextures/setRGBA-equivalent buffers
(texture_indices from tasks, gpu_textures, diff_rgb_combo, color_weights, generate_RBGA_params),
cuFuncSetAttribute(textures_accumulate, MAX_DYNAMIC_SHARED_SIZE_BYTES, shared_size) for the CDP
child, launch textures_nonoverlap <<<1,1>>> (18 args), de-interleave diff_rgb_combo. tp_tex_selftest.

RESULT on RTX 5060 Ti: textures_nonoverlap + its CDP child textures_accumulate EXECUTE correctly
(no errors, shared 58880, 5120 tiles, output rms within ~1% of golden) => Blackwell compatibility
confirmed. BUT diff_rgb_combo does NOT match the Jul-2025 golden numerically (value layers off by
constant ~268, diff layers diff_sigma-sensitive). Ruled out input-CLT sensitivity (same error with
golden CLT), diff_sigma (10.0 closest), arg/param order. NOT used by the LWIR16 CUAS workflow
(cuas/ uses only convert_direct/corr2D_normalize/imclt_rbg_all). Documented known issue (golden
staleness / unverified RGB-path drift), to track later via git bisect + the 107 kernel branch switch.
