Summary: Hi team, I'm from Microsoft and recently I'm working on improving Python ecosystem support for Windows on Arm. So I updates the CI workflows to add support for Windows ARM64 build and release. Could you please help to review? Thanks. **Windows ARM64 support and OpenBLAS installation improvements:** * Added a new PowerShell script `install-openblas.ps1` that automatically detects the runner architecture (x64 or ARM64), downloads the appropriate OpenBLAS binary, verifies its hash, and installs it to `C:\openblas`. This ensures consistent and secure OpenBLAS setup on all Windows runners. * Updated the build matrix in `.github/workflows/build-pip.yml` to include `windows-11-arm`, enabling CI builds and tests on Windows ARM64 runners. * Refactored the Windows `before-all` build step in `pyproject.toml` to use the new PowerShell script, replacing the previous hardcoded x64-only download command. This allows seamless support for both x64 and ARM64 architectures.
