[FEATURE] Editor button should open project in a new window

Problem Statement

Clicking the VS Code/Cursor button in the Claude Code desktop app opens the project in the existing editor window, replacing my currently open project.

This breaks my workflow every time I switch between projects in Claude Code while already having work open in my editor.

Expected behavior

The button should open the project in a new editor window (equivalent to code --new-window . / cursor --new-window .), so the user's existing workspace is preserved.

Proposed Solution

Either:

• Always pass --new-window when launching the editor from the button, or
• Add a setting (e.g. "editorNewWindow": true) to let users control this behavior

Context

macOS, Claude Code desktop app. Reproducible every time the button is clicked when an editor window is already open.
