🤖[deprecated] Generated by Copilot at dd28e6e

• Add logic for reporting completion requests and user feedback to the AI service using the IAIReporter interface (link, link, link, link, link, link, link, link, link, link)
• Refactor some variables to use const instead of let to indicate that they are not reassigned and improve readability (link, link, link, link, link, link)
• Simplify the expression for getting the current timestamp in milliseconds by using +new Date() instead of new Date().getTime() (link)
• Remove some unused imports from the completeProvider.ts file (link)

🤖[deprecated] Generated by Copilot at dd28e6e

This pull request enhances the ai-native module with reporting capabilities for the inline completion feature. It defines a new interface IAIReporter and a new type CompletionEvent for sending metrics and events to the AI service. It also updates the completeProvider.ts file to use the aiReporter instance and the AISerivceType.Completion enum value.
