**Omarchy version:** 4.0.1-1

**What happened:**
Once the screensaver (omarchy-launch-screensaver) starts, moving the mouse
does not dismiss it. Only a keypress dismisses it.

**Expected:**
Per the script's own comment, mouse input should also dismiss the screensaver.

**Root cause (verified in source):**
/usr/share/omarchy/bin/omarchy-screensaver has:

    # Exit the screensaver on signals and input from keyboard and mouse
    ...
    while pgrep -t "${tty#/dev/}" -x ttfx >/dev/null; do
        if read -n1 -t 1 || ! screensaver_in_focus; then
          exit_screensaver
        fi
    done

`read -n1 -t 1` only reads bytes arriving on the terminal's stdin, which is
what a keypress produces. Plain mouse movement never appears on stdin because
the script never enables terminal mouse-tracking (no `\e[?1000h`), so the
terminal emulator has no reason to forward mouse events at all. The other
check, `screensaver_in_focus`, only fires if a different window becomes
focused, which plain mouse movement over the fullscreen screensaver window
does not do either.

Separately, the Quickshell idle service
(/usr/share/omarchy/shell/plugins/services/idle/Service.qml,
handleActiveSignal()) deliberately ignores the compositor's idle-monitor
"active" signal once the screensaver window is open, and waits specifically
for the screensaver window to close (a Hyprland closewindow event) — so even
compositor-level mouse-activity detection doesn't reach the dismiss logic.

**Steps to reproduce:**
1. Let the screensaver's idle timeout elapse (idle.screensaver in shell.json).
2. Once the screensaver terminal window appears, move the mouse without
   pressing any key.
3. Screensaver stays up indefinitely; only a keypress dismisses it.

**Suggested fix:**
Enable terminal mouse-tracking mode in omarchy-screensaver (e.g. printf
'\e[?1003h' on start / '\e[?1003l' on exit) and read mouse-motion escape
sequences in the read loop, or otherwise have the launching side listen for
raw pointer motion (e.g. via the compositor) instead of relying on terminal
stdin.
