feat: handle laptop lid state in brightness-display

[Acoowa]

Overview

This PR improves the system wake behavior for laptop users. Currently, omarchy-system-wake (via omarchy-brightness-display) unconditionally enables all displays. This causes the internal laptop screen to turn on even when the lid is closed, which is often undesirable when using an external monitor.

Changes

• Added a check for the laptop lid state using /proc/acpi/button/lid/.
• Dynamically detects the internal monitor name (e.g., eDP-1) using hyprctl.
• If the lid is closed and an external monitor is connected, the internal display is disabled before triggering DPMS.
• If the lid is open, it ensures the internal display is re-enabled with preferred settings.
• Added a fallback to ensure the script doesn't break if jq is not installed or if it's running on a desktop without a lid sensor.

Why this is needed

When a laptop is docked or connected to a TV, waking the system shouldn't light up the screen under the closed lid. This prevents "ghost" windows from being placed on an invisible screen and saves power/heat.

Testing

Tested on a laptop with an external monitor setup.

• Lid closed + Wake: Only external monitor turns on.
• Lid open + Wake: Both monitors turn on.
