Portrait (9:16) screensaver: OMARCHY stacked top to bottom

[Jijjy]

The stock screensaver wordmark is a wide landscape OMARCHY (logo.txt → ~/.config/omarchy/branding/screensaver.txt). Looks great on 16:9. On a portrait monitor the wordmark gets clipped — the sides fall off the screen instead of fitting.

Please ship a 9:16 variant with OMARCHY spelled top to bottom — one letter stacked on the next — and pick it when the monitor is portrait.

omarchy-launch-screensaver already opens one fullscreen terminal per monitor, so mixed landscape + portrait desks could get the matching art on each screen.

Users can paste custom ASCII into screensaver.txt today, but the stock branding should love portrait monitors the same way it loves 16:9.
