Add Branch State Management with Telemetry

This PR adds intelligent branch state tracking to the Codacy IntelliJ extension. It monitors what type of branch the user is currently working on and sends telemetry data about branch state changes.

Key Changes:

• 4 Branch States: Tracks if user is on a PR branch, analyzed branch, outdated analyzed branch, or unknown branch
• Smart Detection: Automatically determines branch state by checking PR status and comparing local commits with Codacy's analysis
• Telemetry Events: Sends BranchStateChangeEvent when users switch between different branch types
• New API Integration: Added endpoint to fetch enabled branches from Codacy

What It Does:

• When you open a repository, it fetches the list of analyzed branches from Codacy
• Continuously monitors your current branch and determines its state
• Tracks when you switch between different types of branches (PR → analyzed → unknown, etc.)
• Sends anonymous telemetry data to help improve the product

Files Changed:

• Added branch listing API method and response model
• Enhanced RepositoryManager with state management logic
• Integrated with existing telemetry system

What's missing:

• Adding OrgId to all events
