Greptile Summary

This PR enhances the user experience in the CLI's buy functionality by addressing potential confusion around zone and instance type precedence. The changes implement two key improvements:

Warning System: When users specify both a zone/cluster and an instance type, the CLI now displays a console warning explaining that the zone takes precedence over the instance type. This prevents user confusion about which parameter will actually be used.

Enhanced Quote Display: The quote display logic has been improved to show more meaningful information when working with zones. Instead of displaying the generic instance type (which would be ignored anyway), the system now fetches zone metadata from the /v0/zones API endpoint and displays the zone's delivery type and hardware type in a formatted string like "Kubernetes (h100v)" or "Virtual Machine (h100v)".

The implementation adds a new getZoneMetadata function that queries the zones API to retrieve delivery type and hardware type information. A local DeliveryTypeMetadata mapping converts API delivery types ("K8s", "VM") to user-friendly display names ("Kubernetes", "Virtual Machine"). This change integrates well with the existing quote display system and maintains consistency with how instance types are presented elsewhere in the codebase.

These changes fit naturally into the existing buy workflow, enhancing the preAction hook with the warning logic and the quote display section with the improved type information, making the CLI more informative and user-friendly.

Confidence score: 4/5

• This PR is safe to merge with minimal risk of breaking existing functionality
• Score reflects straightforward logic additions with proper error handling and fallbacks
• Pay attention to the API integration in the getZoneMetadata function for potential network-related edge cases
