FEATURE: Multi-window support in Claude Code Desktop

## Feature Request **Claude Code Desktop should support opening multiple windows within a single app instance.** ### Current Behavior - Desktop is a single-window app with a sidebar-based session manager - You can create multiple sessions, but can only view one at a time by clicking between them in the sidebar - The only way to view two sessions side by side is to launch a second app instance via `open -n -a "Claude"`, which doubles memory usage ### Requested Behavior - Ability to open a new window (e.g., Cmd+N or File > New Window) within the same app instance - Each window can display a different session - This allows users to view and work on two sessions side by side without the overhead of running multiple app instances ### Why This Matters - Side-by-side comparison of sessions is a common workflow (e.g., referencing one session's output while working in another) - Running two full app instances just to see two sessions is wasteful on memory - Every major productivity app (browsers, editors, terminals, Finder) supports multiple windows — this is table stakes UX - The sidebar session switcher works for managing sessions, but forcing single-window view limits productivity ### Workarounds (all suboptimal) 1. `open -n -a "Claude"` — works but doubles memory usage 2. Desktop + CLI terminal side by side — inconsistent experience 3. Desktop + claude.ai/code in browser — fragmented workflow 4. Rapidly clicking between sidebar sessions — defeats the purpose of parallel work
