feat(ahk): autoload config on start

When AutoHotKey is detected, and %USERPROFILE%\komorebi.ahk exists,
komorebi.exe will now try to run the ahk script after starting the
command listener.

For this to work smoothly, it is important to set the #SingleInstance
directive to Force in komorebi.ahk, which will ensure that duplicates of
the script are not run, and a new version of the script is loaded
without displaying a GUI confirmation prompt.

 You can similarly stop the process by running `komorebic stop`.
 
+If you have AutoHotKey installed and a `komorebi.ahk` file in your home directory (run `$Env:UserProfile` at a
