CLAUDE: test_pose_corr_jna - the tol-0 verdict binary (NVRTC production module); direct test = stepping companion

RUNG 1 VALIDATED on the first real v013 case (scene 1773135467_917220,
4 LMA iterations, 150 tiles/set, 300 corr tiles/iter): test_pose_corr_jna
PASS BIT-EXACT @tol 0 - tasks (calculate_tiles_offsets) and raw TD
correlation (correlate2D_inter) both max|diff|=0, every iteration.

The offline-nvcc direct-launch binary (src/tests/test_pose_corr) cannot be
bit-exact vs the NVRTC JIT (FMA/codegen divergence), measured: -G -O0 ->
tasks off by 2^-13 px; RELEASE=1 -> tasks BIT-EXACT, corr within ~1 ULP at
operand scale (max|diff| 128..256 vs amplitudes ~2e9, float spacing 256).
Role split documented in both headers (same pairing as test_avg_td_oob /
test_proc_consolidate): direct binary for cuda-gdb stepping, _jna binary
for the production-equivalence verdict. Build line in the _jna header.
