FYI this is sitting on top of feature/grouped-view-headers since that should be merged first, and this adds the new options in the header too.

Overview

Introduces a new view mode toggle for the File History view that allows users to switch between viewing commits and contributors for a specific file or folder.

Changes

• New view mode toggle: Adds "View Contributors" and "View Commits" buttons to switch between display modes
• Contributors integration: Leverages existing contributor functionality to show file-specific contributor statistics
• Context awareness: Automatically resets to commits mode when cursor following is enabled since line ranges aren't supported for contributors
• Menu reorganization: Reorganizes existing menu items to accommodate the new mode toggle buttons
• Telemetry support: Adds tracking for the new mode switching commands

Benefits

• Provides users with multiple perspectives on file history - both chronological commits and contributor-based views
• Enhances the existing contributor functionality by making it accessible at the file level
• Maintains consistency with existing view patterns while expanding functionality
• Offers more flexibility for analyzing file ownership and contribution patterns
