### What happens

Editing a local plugin's QML (`~/.config/omarchy/plugins/<id>/Panel.qml`, `Service.qml`, ...) logs

```
DEBUG qml: Local plugin changed, reloading: io.github.diogo7dias.omaclack
```

but the shell keeps running the QML it compiled earlier. The edit only appears after `omarchy restart shell`, so plugin hot reload never actually applies a change.

### Why

`shell.qml`, `finishPluginReload` (line 1459 in 4.0.3-1, unchanged on master as of 31bd80d):

```qml
if (typeof Qt.clearComponentCache === "function") Qt.clearComponentCache()
shell.pluginRegistry.rescan()
```

QML's `Qt` object has no `clearComponentCache` — it is a `QQmlEngine` C++ method, not part of the QML global. The condition is therefore always false and the call never runs, so `rescan()` re-registers the plugin and the engine hands back the types it already compiled from the same file URLs.

### Repro

1. Install any local bar-widget plugin under `~/.config/omarchy/plugins/<id>/`.
2. Open its panel.
3. Change a visible string in its `Panel.qml` and save.
4. The shell logs `Local plugin changed, reloading: <id>`; reopen the panel — the old text is still there.
5. `omarchy restart shell` — the new text appears.

### A fix, and its catch

Replacing the local-plugin path with a soft engine reload does work; I ran it here for a while and edits showed up in well under a second, with windows preserved:

```qml
Timer {
  id: localPluginReloadTimer
  interval: 150
  onTriggered: Quickshell.reload(false)
}
```

The catch is blast radius. The watcher fires for *any* file written inside a plugin directory, not just QML, so plugins that write there at runtime would reload the entire shell repeatedly. That is not hypothetical: a plugin of mine ships a Python helper, and merely importing it creates `bin/__pycache__/*.pyc` inside the plugin directory, which triggered a full reload every time.

Narrowing it would avoid that — reload only when the changed path ends in `.qml`, or only under an opt-in dev flag, and keep the cheap registry path for enable/disable. I did not want to pick that design in a drive-by PR, but I am happy to send a patch in whichever shape you prefer.

### Environment

omarchy 4.0.3-1, Quickshell 0.3.1, Arch Linux, Hyprland.
