fix(ci): use native ARM64 runner for Linux aarch64 wheel build

[goldmedal]

Summary

• Switch Linux aarch64 wheel build from cross-compilation on ubuntu-latest (x86_64) to native ubuntu-24.04-arm runner
• Fixes ring crate build failure: #error "ARM assembler must define __ARM_ARCH" when cross-compiling with aarch64-unknown-linux-gnu-gcc

Root Cause

The ring crate's assembly files require __ARM_ARCH to be defined by the compiler. When cross-compiling on x86_64 with the GCC cross-compiler, this macro is not set, causing the build to fail. Using a native ARM64 runner eliminates cross-compilation entirely.

Test plan

• Trigger pypi-publish.yml workflow and verify all 5 wheel builds pass

📝 Walkthrough

Walkthrough

The PyPI publishing GitHub Actions workflow was updated to use a native ARM64 runner (ubuntu-24.04-arm) instead of the x86_64 ubuntu-latest runner for building wheels targeting the aarch64-unknown-linux-gnu platform. All other workflow logic remains unchanged.

Changes

Cohort / File(s)	Summary
CI/CD Workflow Configuration .github/workflows/pypi-publish.yml	Updated the wheel-build matrix to use native ARM64 runner (ubuntu-24.04-arm) for aarch64 architecture builds instead of x86_64 ubuntu-latest.

Poem

🐰 Hopping swift on forty-eight's bright ARM,
No more the x86 shall cause alarm,
Native runners now build wheels so fine,
For aarch64 platforms, a perfect design! ✨
