feat: GUI dashboard, system Proton scanning, and XDG autostart

GUI dashboard (gui.rs):
- Add detect, diagnose, settings panel, per-launcher games management
- Async Kill with optimistic UI state and rollback on error
- Settings: pick_list for Proton version, browse button for compat dir,
  validation, per-launcher version badge
- Detect Installed button with scan results in footer
- Diagnose card with ✓/✗ checklist per launcher

Issue #1 — Use System Proton (proton.rs):
- Extend list_installed() to scan ~/.steam/root/compatibilitytools.d,
  ~/.local/share/Steam/compatibilitytools.d, and
  /usr/share/steam/compatibilitytools.d in addition to the configured
  compat dir; deduplicates by name so the same version never appears twice

Issue #4 — Remove Systemd Service (service.rs):
- Replace systemd unit management with XDG autostart:
  install() writes ~/.config/autostart/umutray.desktop instead of a
  systemd unit and never calls systemctl; uninstall() removes that file;
  status() checks whether the autostart entry exists
- Update GUI service_is_installed() to check the XDG autostart path
