Sphere v0.1.2 - Enhanced Error Handling

This release focuses on improving the robustness and user-friendliness of Sphere when encountering issues with dependency files.

Key Fixes:

• Improved Error Message for Missing Dependency Files: If a .sphere file lists a dependency that is correctly indexed in ~/.sphere/cache/index.json but the actual dependency .sphere file is missing from the cache directory, Sphere will now provide a clear, detailed error message specifying the missing file, its expected Sphere ID, its alias, and the full path where it was expected. This replaces the previous generic "No such file or directory" error, making it much easier for users to diagnose and fix cache or installation issues. (Fixes GitHub Issue #2 )

This update makes Sphere more resilient to common file system issues and provides better guidance to users.

Thanks to our founding team for their diligent testing and implementation!
