v0.1.2

Tray icon fix.

• Listen for the TaskbarCreated broadcast and re-register the tray icon after Explorer restarts.
• Re-register once 20 seconds after startup so a boot race with Explorer cannot swallow the icon.

No config changes; existing config.ini keeps working.

v0.1.1

Guard comes back if something quits it externally; stopping one host no longer stops another host guard.
