Windows Build Artifact Fix

Ollama v0.17.8-rc3 resolves a CI pipeline issue that prevented Windows zip files from being properly included in release artifacts. This ensures users on Windows can properly download and install the latest version.

Compression Improvements

The release implements two key optimizations to manage build size constraints:

• 7z Compression: The build process now uses 7z compression (when available in the build path) instead of standard zip, achieving a significantly better compression ratio
• Discrete MLX Download: The machine learning extensions (MLX) component is now split out as a separate download rather than bundled into the main installer, allowing the primary Windows package to remain under the 2GB threshold

CI Reliability Enhancements

The CI/CD pipeline has been strengthened with explicit failure reporting when artifact uploads encounter issues, improving visibility into build problems and preventing silent failures from going undetected.

These changes ensure reliable distribution of Windows binaries while maintaining manageable download sizes for all users.
