Greptile Summary

This PR enables Windows builds in the Daft project's CI/CD pipeline by fixing platform-specific virtual environment handling. The changes span two GitHub Actions workflow files to properly support Windows wheel building alongside existing Ubuntu builds.

The primary fix is in build-wheel.yml where the virtual environment activation logic is updated to handle Windows' different directory structure. On Windows, Python virtual environments store activation scripts in Scripts/ directory rather than bin/, requiring platform-specific path handling. The code now conditionally sets the correct PATH and uses the appropriate activation command based on the operating system.

The publish-dev-s3.yml workflow is extended to include Windows in its build matrix, adding windows to the OS options while excluding the unsupported windows-aarch64 combination. This enables Windows wheel distribution to S3 for development builds.

These changes integrate with Daft's existing build infrastructure by leveraging the reusable build-wheel.yml workflow that's called from multiple contexts. The fix ensures that the same build process can work across both Unix-like systems and Windows without breaking existing functionality.
