Refactor codebase: improve method organization and remove redundancies

[Copilot]

This PR addresses code quality issues by refactoring the codebase to improve maintainability, readability, and organization. The changes focus on eliminating duplicate code, breaking down overly complex methods, and cleaning up unused imports.

Key Changes

🔧 Fixed Code Duplication

• Removed duplicate DOM assignment in BreakpointCapture.updateFrameInfoDom() where frameInfoDom.innerHTML was being set twice
• Eliminated redundant wrapper method vscodeOpen() in BreakpointCapture class that simply called the global function

📦 Method Extraction and Organization

Refactored the monolithic procImagePanel() method in VariableTracker (80+ lines) into smaller, focused methods:

• initializeImagePanel() - Handles panel initialization and settings loading
• setupSessionTracker() - Manages debug session tracking setup
• fetchVariables() - Handles variable fetching and logging
• processImageVariables() - Processes image variables and generates metadata
• renderImagePanel() - Manages panel rendering and display
• setImageWebUrls() and displayImages() - Helper methods for image display

🧹 Code Cleanup

• Removed unused import register from module in tracker.ts
• Cleaned up large commented code blocks (30+ lines of dead code)
• Improved code consistency and formatting

Impact

• Improved maintainability: Smaller, focused methods are easier to understand and modify
• Better testability: Individual methods can be tested in isolation
• Enhanced readability: Code is more self-documenting with descriptive method names
• Reduced complexity: Breaking down the large method reduces cognitive load

All changes maintain existing functionality while significantly improving code quality. The extension continues to work exactly as before, but the codebase is now more maintainable for future development.
