## What happened

On a 3-monitor setup, `omarchy-launch-screensaver` reliably opens the screensaver on the first 2 monitors it iterates but times out silently on the 3rd, leaving that monitor with no screensaver. The script still exits 0, so nothing looks wrong from the logs — the idle daemon just sees a normal `idle-cycle-start` -> `process-exit: screensaver exitCode=0` cycle every time.

## Expected

Screensaver opens on every connected/enabled monitor.

## Steps to reproduce

1. Connect 3 monitors (repro system: laptop panel `eDP-1` + 2 external `DP-3`, `DP-4`).
2. Run `omarchy-launch-screensaver force` (or let idle timeout trigger it).
3. Watch `hyprctl`'s event socket while it runs.

## Diagnosis

Captured `.socket2.sock` events live during a `force` run:

```
focusedmon>>eDP-1,4
focusedmonv2>>eDP-1,4
openwindow>>...,4,org.omarchy.screensaver,Ghostty   # OK
focusedmon>>DP-3,1
focusedmonv2>>DP-3,1
openwindow>>...,1,org.omarchy.screensaver,Ghostty   # OK
focusedmon>>DP-4,3
focusedmonv2>>DP-4,3
# no openwindow event follows for DP-4 — 5s deadline in
# wait_for_screensaver_window() elapses, loop moves on
focusedmon>>DP-3,1                                   # script returns focus to original monitor
focusedmonv2>>DP-3,1
```

`wait_for_screensaver_window()`'s 5s deadline (in `/usr/share/omarchy/bin/omarchy-launch-screensaver`) isn't consistently enough time for the 3rd Ghostty spawn in the per-monitor loop — the script's own comment acknowledges the race ("otherwise slow-starting terminals all pile onto the last monitor") but the fallback here is a silent timeout + skip rather than a pile-up, so that monitor just never gets a screensaver window.

Also confirmed NOT caused by:
- idle config (`~/.config/omarchy/shell.json` `idle.screensaver`/`idle.lock` fire correctly, verified in `journalctl --user`)
- `screensaver-off` toggle (unset)
- missing `ttfx` (present, v0.3.2)
- Ghostty `gtk-single-instance` (already `false`)
- Bluetooth/USB HID noise or an idle-inhibitor on the terminal window (`inhibitingIdle: false`)
