feat(build): add Linux aarch64 support

This commit adds support for building Linux ARM64 wheels:

- Add aarch64 to Linux build matrix
- Configure platform-specific containers and tags
- Update pyproject.toml to support both x86_64 and aarch64
- Add Linux classifier to package metadata

These changes enable building wheels for both x86_64 and aarch64
architectures on Linux while maintaining manylinux2014 compatibility.
