Problem

After analysis, it was discovered that state change telemetry events were not being properly emitted by the IntelliJ extension. The extension was missing critical telemetry tracking for repository, pull request, and branch state transitions, which are essential for analytics and monitoring user behavior across different IDE extensions.

Solution

This PR implements comprehensive telemetry state change tracking to match the VS Code extension behavior and includes several improvements for better IDE and OS parameter normalization.

Changes Made

🔧 Telemetry State Change Events

• Added Repository State Change tracking: Now emits events when repository state transitions (Initializing, NeedsAuthentication, NoGitRepository, Loaded, NoRepository)
• Added Pull Request State Change tracking: Tracks PR state transitions (NoPullRequest, Loaded)
• Modified state change detection: Events are only emitted when state actually changes, preventing duplicate telemetry
• Standardized OS & IDE conventions

Missing components

• Tracking branch state change is missing. Requires understanding analysed branches. we dont pull that info yet. might as well open a new PT
• Missing OrgID for parity with VScode

Looks good to me. I think. If we can test it locally and see events propagated, we're golden.

Made some changes, I need clarification on this one if statement, I think its too convoluted
