fix: close window quits app instead of hiding to tray

No system tray is shown, so hiding the window on close left the app
running with no way to quit except Ctrl+C. Now closing the window
sets isQuitting=true and lets the normal close flow proceed, which
triggers before-quit → stopServer().

Bumps version 0.9.4 → 0.9.5.
