Summary of repair for failed_python-safetensors

Root cause:
- During wheel build, PyO3 (Rust crate used by safetensors) detected the configured Python interpreter version 3.13 is newer than PyO3's maximum supported version (3.12). The PyO3 build script fails with:
  "error: the configured Python interpreter version (3.13) is newer than PyO3's maximum supported version (3.12)"
- This caused maturin/pip to fail building the Rust extension and the RPM %build stage to exit with error.

Minimal fix applied:
- Allow building against a newer Python by enabling PyO3's ABI3 forward compatibility. This suppresses the PyO3 version check and builds using the stable ABI.

Files modified (all paths relative to temp_workspace/failed_python-safetensors):
- python-safetensors.spec
  - Inserted a single-line environment export in %build and %install sections:
    export PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1
  - The export lines were placed immediately before entering the bindings/python directory in each section (minimal change to ensure the environment is set for both build and install phases).

%description
This repository implements a new simple format for storing tensors safely (as
opposed to pickle) and that is still fast (zero-copy).

OBS upload:
- The repaired package directory was uploaded to OBS. Upload tool returned: Success: File temp_workspace/failed_python-safetensors uploaded to OBS failed_python-safetensors successfully.

Notes and rationale:
- This change is intentionally minimal: it only sets a documented PyO3 environment variable to permit building against the newer system Python. The alternative would be to update the PyO3 dependency in the package sources (upstream/library), but that is a larger change that touches package contents.
- Setting PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1 is recommended by PyO3 as a way to build with newer Python when the crate hasn't yet updated its explicit compatibility check. It uses the stable ABI and is a safe, minimal approach for packaging.

If build still fails after this change, next steps:
- Re-run the build to confirm. If a different error appears, gather the next failing log section and iterate.
- If ABI3 forward compatibility is insufficient (rare), consider pinning to a Python version supported by upstream or patching the pyproject to update PyO3.
