Bump pypa/gh-action-pypi-publish from 1.14.2 to 1.14.3 in /.github/workflows - #4942

Integrate thirteen official upstream commits after the private GPU cleanup
checkpoint. Preserve blocking host-sync selection and its CUDA 12.0/12.1
flag boundary while adopting upstream's generalized compute-capability
helper and LoMa/FlexGlue callers. Keep both capability and policy tests;
remove the duplicate colmap_util_cuda link from automatic composition.

Includes upstream rig-frame covisibility, thin bitmap thumbnails, visibility
coordinate conversion, row-wise warp dispatch, benchmark fixes, FlexGlue,
review guidance, and the Windows non-GUI SIFT-test build fix.

Validation at this private checkpoint: merge conflicts resolved in cuda.cc,
cuda.h, cuda_test.cc; source search found no remaining old BF16-helper call;
git diff --check passed. Native merged-source qualification and independent
exact-diff review remain pending. Prior GPU tests qualify their pinned source,
not this entire merged product. No reconstruction or performance claim.

AI-assisted integration. Existing published history is preserved.

Refresh the experimental alternative with fork main while retaining its previous head as a parent. The resulting tree is exactly main plus the isolated shared-current-cost-cache deletion: one CUDA file, +1/-25.

## Change

Read the existing cost map directly during the ordered sampled-cost fold. Preserve current plane propagation, source packing, scheduling and fallback mathematics. The cache originates in custom a37c1c3, MVS: Reuse sampled current costs (GPU perf). The earlier alternative is retained through 8481f89; its original experiment was 8b1412f.

Historical Fountain11 photo+geometry at 3072 recorded 76.85 -> 78.82 seconds, one observation per arm, on the older revision. Retain this inconclusive/adverse observation with its earlier revision; current performance has not been measured. No performance experiment was reopened.

## Validation

- Exact candidate CUDA owner compiled with CUDA 13.2 for compute_86/sm_86. In a bounded retained-support context on RTX 3060, both matched targets passed all 13 selected cases: propagation, ordered source folding, checkpoint-HMM and paired-sweep preservation.
- Four complete inputs and four outputs matched across executables: 8,492,128 bytes per arm. Maps were finite with positive depth and checked ordered graph IDs. Complete witnesses use checkpoint_hmm=false; separate checkpoint tests cover both settings without full cross-executable true-mode witnesses.
- Direct owners, link maps and actual loaded providers were checked; managed jobs ended and released their bookings. Later host resize/warp changes have separate owner qualification. This is not a whole-branch build, reconstruction-quality, portability or current-performance result.
