claude-vscode.editor.open always opens tab in first/primary VS Code window instead of focused window

Bug

When multiple VS Code windows are open (including across macOS desktops/Spaces), running claude-vscode.editor.open via the command palette or keybinding always opens the Claude Code tab in the leftmost/primary VS Code window, not the currently focused one.

Steps to reproduce

1. Open two VS Code windows (optionally on different macOS desktops)
2. Focus the second (non-primary) window
3. Run claude-vscode.editor.open via Cmd+Shift+P or keybinding
4. The Claude Code tab opens in the first window, not the focused one

Note: The command palette itself appears in the correct (focused) window - it's only the resulting tab that opens in the wrong window.

Expected behavior

The Claude Code tab should open in the currently focused VS Code window.

Environment

• macOS 24.6.0 (Darwin)
• Claude Code extension v2.1.68
• VS Code latest
• Apple Silicon (arm64)
