hyprctl keyword monitor cannot re-enable a disabled monitor

## Description After disabling a monitor via `hyprctl keyword monitor "eDP-1, disable"`, attempting to re-enable it via `hyprctl keyword monitor` has no effect. The monitor stays dark. TTYs are also black (output disabled at KMS level). Only a full Hyprland restart restores it. ## Steps to reproduce ```sh hyprctl keyword monitor "eDP-1, disable" sleep 2 hyprctl keyword monitor "eDP-1, preferred, auto, 1" # or with explicit resolution: hyprctl keyword monitor "eDP-1, 1920x1080@60, 0x0, 1" ``` Expected: monitor comes back on. Actual: monitor stays off. TTYs also black. ## Workaround DPMS works as a substitute for simple blanking: ```sh hyprctl dispatch dpms off eDP-1 hyprctl dispatch dpms on eDP-1 ``` DPMS does not fully disable the output (workspaces remain assigned), so it is not a complete equivalent — but it restores the display reliably. ## Context - Hyprland 0.55.2 - Arch Linux, laptop internal display (eDP-1) - Use case: lid switch binds — disable internal panel on lid close, re-enable on lid open - Related: #14447 fixed re-enabling monitors via the Lua config API (`hl.monitor.disabled = false`). The `hyprctl keyword monitor` IPC path has the same underlying problem but was not addressed by that PR. ## Config ```ini bindl=,switch:on:Lid Switch,exec,hyprctl keyword monitor "eDP-1, disable" bindl=,switch:off:Lid Switch,exec,hyprctl keyword monitor "eDP-1, preferred, auto, 1" ```
