Description

Extract three CUDA 12 utility fixes from the migration work for independent review:

  • Accept bytes options in nested resource conversion.
  • Retain borrowed coredump buffers and free getter allocations.
  • Preserve KeyError raised inside a registered handle getter.

Includes focused regression coverage and release notes. Matching main PR: #3356.

Validation

Fresh CUDA 12.9 build; 94 focused tests passed. All 58 CI jobs passed, including the coredump and new GPU regression paths. Changed-file pre-commit checks passed; the full local check encountered existing findings in unchanged files.
