Subject: [PATCH] Add systemd timers to auto-mute/unmute when idle-inhibit is
 active

Mutes audio at 21:00 and unmutes at 07:00, but only when the
idle-inhibit toggle is active (PID file exists). This is useful
for leaving the computer running overnight for SSH access while
keeping it quiet for sleeping.

+To enable the auto-mute/unmute timers (mutes at 21:00, unmutes at
+07:00, only when idle-inhibit is active), link the systemd user units:
+
+```
+systemctl --user link ~/Projects/hypr-dotfiles/systemd/user/auto-mute.service
+systemctl --user link ~/Projects/hypr-dotfiles/systemd/user/auto-mute.timer
+systemctl --user link ~/Projects/hypr-dotfiles/systemd/user/auto-unmute.service
+systemctl --user link ~/Projects/hypr-dotfiles/systemd/user/auto-unmute.timer
+systemctl --user enable --now auto-mute.timer auto-unmute.timer
+```
