ci: add hook consistent check

[halfcrazy]

Summary

This PR adds a mandatory static consistency gate for CUDA hook registrations and fixes existing inconsistencies in the hook chain.

What’s included

• Add a new static checker script:
  • hack/check_cuda_hook_consistency.py
• Enforce consistency checks across:
  • src/cuda/hook.c (cuda_library_entry[])
  • src/include/libcuda_hook.h (cuda_override_enum_t)
  • src/libvgpu.c (DLSYM_HOOK_FUNC(...))
  • wrapper function definitions in src/cuda/*.c and src/libvgpu.c
• Wire the checker into CI as a required gate:
  • add hook-registry-check job in .github/workflows/build-src.yml
  • make BuildHamiCoreLib depend on this job (needs)
• Add local make target:
  • make check-cuda-hook-consistency

Consistency fixes included in this PR

• Align enum order with hook table:
  • fix cuMemcpy2D_v2 / cuMemcpy2DUnaligned_v2 order mismatch in src/include/libcuda_hook.h
• Complete dlsym hook registration:
  • add DLSYM_HOOK_FUNC(cuMemFreeAsync) in src/libvgpu.c
• Remove duplicated dlsym hook entries in src/libvgpu.c:
  • duplicate cuDeviceGet
  • duplicate cuMemcpyDtoDAsync_v2

Why

Historically, CUDA API additions required synchronized updates across multiple files, which is error-prone and can silently leave gaps (especially in dlsym/cuGetProcAddress paths).
This PR turns that into an automated, deterministic CI gate to prevent regressions.

Test Plan

• Run local check:
  • make check-cuda-hook-consistency
• Verify checker passes on current tree:
  • python3 hack/check_cuda_hook_consistency.py
• Verify no lint issues introduced in touched files
• Verify CI workflow contains and runs hook-registry-check before build

Risk / Impact

• Low runtime risk.
• Main impact is process hardening:
  • PRs that introduce hook registration mismatches or duplicates will now fail fast in CI.
