## What happened

On a laptop where the internal panel (`eDP-1`) is manually force-disabled while docked (via `omarchy-hyprland-monitor-internal off`, e.g. from a custom `monitor.added` hook in `monitors.lua`), unplugging the external monitor's cable leaves the internal display off **permanently**. It never recovers, even though Omarchy's monitor watcher (`omarchy-hyprland-monitor-watch`) is running and reacting to the `monitorremoved`/`monitorremovedv2` events.

## Expected behavior

Per the comments in the default `monitors.lua` template ("Omarchy's monitor watcher turns it back on again when the external one goes away"), the internal panel should be automatically re-enabled once no external monitor is connected.

## Root cause

`omarchy-hyprland-monitor-external-active` is:

```sh
hyprctl monitors all -j | jq -e '.[] | select(.name | test("^(eDP|LVDS|DSI)-") | not) | select(.disabled == false)' >/dev/null 2>&1
```

When the internal panel is disabled and the external monitor is then unplugged, Hyprland refuses to leave the session with zero active outputs and substitutes an auto-generated placeholder monitor named `FALLBACK` (`disabled: false`). Since `FALLBACK` doesn't match the `^(eDP|LVDS|DSI)-` exclusion pattern, `omarchy-hyprland-monitor-external-active` matches it and keeps returning **true** — "an external monitor is active" — indefinitely, even with nothing physically connected.

This check is used both by `omarchy-hyprland-monitor-internal recover` (called from `omarchy-hyprland-monitor-clamshell`, which the watcher invokes on every `monitorremoved`/`monitoradded` event and on a 2s poll while docked) and by `omarchy-hyprland-monitor-clamshell`'s own `enable_internal()`. Both silently no-op because the check never flips to false, so the internal panel is never recovered — there's no error, no timeout, it's just stuck.

## Steps to reproduce

1. On a laptop with `omarchy-hw-clamshell`-independent forced internal-disable while docked (e.g. via a custom `hl.on("monitor.added", ...)` hook calling `omarchy-hyprland-monitor-internal off`, not requiring the lid to be closed), connect an external monitor. Internal panel correctly disables.
2. Unplug the external monitor's cable and leave it unplugged.
3. Observe: `hyprctl monitors all -j` now shows a `FALLBACK` output in place of the real one, `eDP-1` stays `"disabled": true` indefinitely, and `omarchy-hyprland-monitor-external-active` keeps exiting 0 (true).

## Live evidence

Captured via polling `hyprctl monitors all -j` and `omarchy-hyprland-monitor-external-active` once per second across an unplug event that was left disconnected:

```
14:02:50 ext_active=yes hw_ext=yes mons=[{"n":"eDP-1","d":true},{"n":"HDMI-A-1","d":false}]
14:02:51 ext_active=yes hw_ext=no  mons=[{"n":"eDP-1","d":true},{"n":"FALLBACK","d":false}]
14:02:52 ext_active=yes hw_ext=no  mons=[{"n":"eDP-1","d":true},{"n":"FALLBACK","d":false}]
...
14:03:44 ext_active=yes hw_ext=no  mons=[{"n":"eDP-1","d":true},{"n":"FALLBACK","d":false}]
```

`hw_ext` is `omarchy-hw-external-monitors` (sysfs DRM `status`, correctly reports "no" once physically disconnected). `ext_active` is `omarchy-hyprland-monitor-external-active`, which incorrectly stays "yes" for the entire ~53s window because of the `FALLBACK` output.

## Suggested fix

Exclude the `FALLBACK` output (and any other Hyprland-internal placeholder outputs) in `omarchy-hyprland-monitor-external-active`, e.g.:

```sh
hyprctl monitors all -j | jq -e '.[] | select(.name | test("^(eDP|LVDS|DSI)-") | not) | select(.name != "FALLBACK") | select(.disabled == false)' >/dev/null 2>&1
```

## System info

- Omarchy: 4.0.4-1
- Hyprland: 0.56.2 (commit `efb50993780079460b0cbed1363e2166a2de1d9f`)
- Kernel: 7.2.5-3-omarchy
- GPU: Intel HD Graphics 620 (Kaby Lake-U), i915 driver
- Laptop, single internal panel (`eDP-1`) + one external monitor over HDMI

## Workaround in the meantime

Added a second `hl.on("monitor.removed", ...)` hook in my own `monitors.lua` that re-checks for a real external monitor excluding `FALLBACK` and calls `omarchy-hyprland-monitor-internal on` directly when none is found, bypassing the broken built-in check.
