JengaDev v1.0.26

Fixes a launch bug: JengaDev.exe is a console-subsystem binary, so every
launch (desktop icon, Start Menu, login autostart) popped a visible
terminal window - and since that window was the process's own console
host, closing it killed the whole daemon.

The installer now launches the daemon through a hidden-window wrapper
script instead, so no terminal window appears and there's nothing to
accidentally close. No other functional changes.
