fix: prevent sidebar opening in multi-window VS Code setups (#5485)

[roomote]

Fixes #5485

This PR resolves the issue where Roo Code's sidebar would automatically open when the extension is used in another VS Code window, disrupting the user's workflow in multi-window setups.

Root Cause

The issue was in the focusPanel utility function at line 18-19 in src/utils/focusPanel.ts. When no panel was available, it would automatically execute a command to open the sidebar without considering multi-window scenarios.

Changes Made

• Enhanced focusPanel function: Added logic to detect multi-window scenarios before automatically opening the sidebar
• Added shouldAllowSidebarActivation helper: Determines if sidebar activation is appropriate based on:
  • Whether there's already a visible Roo Code instance
  • Whether the current window has active editors (indicating user activity)
  • Conservative approach to avoid disrupting workflow in other windows
• Comprehensive test coverage: Added 8 test cases covering all scenarios including multi-window detection
• Backward compatibility: Maintains existing behavior when appropriate, only prevents unwanted sidebar opening

Testing

• Added comprehensive unit tests for focusPanel functionality (8 test cases)
• Tests cover multi-window detection scenarios
• Verified sidebar opens when expected (single window, visible instance)
• Verified sidebar doesn't open inappropriately (multi-window scenarios)
• Confirmed existing focus behavior for tab and sidebar panels works correctly

Files Changed

• src/utils/focusPanel.ts - Enhanced with multi-window detection logic
• src/utils/__tests__/focusPanel.test.ts - Added comprehensive test coverage

This fix significantly improves the user experience for multi-window VS Code users while maintaining backward compatibility.
