CLAUDE: Step 1 complete — JNA bindings for TpProc imclt/corr + StageProc full validation

TpJna: tp_proc_setup_rbg_corr/exec_imclt/get_rbg/exec_corr2d/get_corr2d_combo + extended
tp_proc_convert_selftest. StageProc validates convert+imclt+corr through the persistent API
(all match goldens) + no_kernels smoke. PASS on 5060 Ti.
