This PR adds a new methodgetReviewerUsers toGitHubRepository class that specifically handles fetching users with reviewer capability. It follows the same pattern asgetAssignableUsers but focuses on reviewer permissions, improving the accuracy of reviewer suggestions by specifically querying for users with reviewer permissions rather than using the broader assignable users list.

Changes

1. NewgetReviewerUsers method inGitHubRepository

• Uses GitHub's GraphQLGetSuggestedActors query with reviewer-specific capabilities
• Tries multiple capabilities in order of preference:CAN_BE_REQUESTED_FOR_REVIEW,CAN_REVIEW,CAN_BE_ASSIGNED
• Gracefully falls back toGetAssignableUsers if suggested actors API is not available
• Includes comprehensive error handling and logging

2. EnhancedFolderRepositoryManager caching

• Added_reviewerUsers cache property and_fetchReviewerUsersPromise for async management
• ImplementedgetReviewerUsers(clearCache?) method with full caching support
• UpdatedgetCachedFromGlobalState andsaveInGlobalState to support 'reviewerUsers'
• Added automatic fetching of reviewer users during repository initialization

3. UpdatedgetReviewersQuickPickItems function

• Now usesgetReviewerUsers() instead ofgetAssignableUsers() for more accurate results
• Renamed variables fromassignableUsers toreviewerUsers for clarity
• Maintains all existing functionality while using reviewer-specific data

4. Unit tests

• Added basic tests to verify new methods exist and can be called
• Tests follow existing patterns in the codebase

Benefits

• More accurate reviewer suggestions: Specifically queries for users with reviewer permissions
• Consistent architecture: Follows the same patterns as existing user fetching methods (getAssignableUsers,getMentionableUsers)
• Robust fallback: Gracefully handles cases where specific reviewer capabilities aren't available
• Improved performance: Separate caching for reviewer users reduces unnecessary API calls
• Better user experience: Reviewer selection UI now uses data specifically tailored for review permissions

Backward Compatibility

The changes are fully backward compatible:

• Existing functionality is preserved through fallback mechanisms
• No breaking changes to public APIs
• Extension works even if new GraphQL capabilities aren't supported by the GitHub instance

Testing

• Code compiles successfully without errors
• Unit tests pass and verify method existence
• Linting passes with no new warnings
• Implementation follows existing code patterns and style guidelines
• Manual verification confirms all expected functionality is implemented

This change improves the accuracy of reviewer suggestions in the PR creation flow while maintaining full compatibility with existing functionality.
