On Windows the daemon shells out to console-subsystem processes without
suppressing the console window. The reaper polls session liveness on a
timer (and the attach loop retries), each call runs a zellij command, and
every invocation pops a console window that instantly closes, so the user
sees rapid blinking.
- Add a platform-split hideWindow(cmd) helper to the zellij package
(CREATE_NO_WINDOW + HideWindow on Windows, no-op elsewhere) and call it
in execRunner.Run so list-sessions and friends stop flashing.
- startBackgroundProcess now uses CREATE_NO_WINDOW instead of
CREATE_NEW_CONSOLE (the latter creates a console then hides it, flashing).
- Pass windowsHide: true to the daemon spawn in main.ts so the daemon's own
console stays hidden on a Windows GUI launch.
