v1.1.0

HDMI Switch v1.1.0

What's new

• Dock detection -- the app now detects whether your device is docked to an external display. When undocked (using only the built-in screen), it silently skips the HDMI switch and WOL entirely. Uses the Win32 QueryDisplayConfig API so it works correctly in all display modes including "Second screen only".
• Silent operation -- removed all popup notifications. The app operates completely silently; status is shown only in the tray icon tooltip on hover.
• Clean codebase -- removed debug logging.
