## Description

The pre-suspend lock screen always fails with:

```
WARN: WlSessionLock.surface does not create a WlSessionLockSurface. Aborting lock.
```

This leaves the session unlocked when the system suspends (lid close, idle timeout, etc.), because the 12s inhibitor budget always expires without securing the session.

## Root Cause

In `/usr/share/omarchy/shell/plugins/lock/Service.qml` (lines 264-288), a `Loader` is placed as a child of `WlSessionLock`:

```qml
WlSessionLock {
    id: sessionLock
    locked: false
    // ...
    Loader {
        active: sessionLock.locked || sessionLock.secure
        sourceComponent: Component {
            WlSessionLockSurface { ... }
        }
    }
}
```

`WlSessionLock` declares `surface` as its default property (`Q_CLASSINFO("DefaultProperty", "surface")`) with type `QQmlComponent*`. The `Loader` (a `QQuickItem`) gets assigned to this property instead of a proper `Component`.

When Quickshell's C++ code calls `mSurfaceComponent->create()` and then `qobject_cast<WlSessionLockSurface*>`, the cast fails because a Loader is not a WlSessionLockSurface.

## Fix

Replace the `Loader` with a bare `Component`:

```qml
WlSessionLock {
    id: sessionLock
    locked: false
    // ...
    Component {
        WlSessionLockSurface { ... }
    }
}
```

`WlSessionLock` manages surface lifecycle internally — it calls `create()` per-screen when `locked` is set to true. No Loader wrapper is needed.

## Environment

- Omarchy: 4.0.1-1
- Quickshell: 0.3.1-1
- Hyprland: 0.56.2-1
- Kernel: 7.1.9-arch1-2

## Workaround

Clone the lock plugin and apply the fix locally:

```bash
omarchy plugin clone omarchy.lock
# Edit ~/.config/omarchy/plugins/<user>.lock/Service.qml
# Replace the Loader block with a bare Component
```
