Gtk4 layer shell not supported

[vafu]

Describe the bug With minimal setup created with agsv2 using gtk4 running the app causes window.vala:52: can not initialize layer shell on window: layer shell not supported

To Reproduce

• ags init
• remove all jsx (since it's not implemented for gtk4 yet), app.ts:

  
  import { App, Astal, Gtk } from "astal/gtk4"

App.start({ main() { const monitor = App.get_monitors()[0] new Astal.Window({ gdkmonitor: monitor, exclusivity: Astal.Exclusivity.EXCLUSIVE, anchor: Astal.WindowAnchor.TOP | Astal.WindowAnchor.LEFT | Astal.WindowAnchor.RIGHT, application: App, child: new Gtk.Button({ label: "button" }) }) }, })

- `ags run`

**Expected behavior**
button widget shown

**Additional context**

LD_PRELOAD=/usr/lib/libgtk4-layer-shell.so ags run fixes it, I assume that should be ensured on ags side?

There is a --gtk4 flag on the run command which does it for you. Unfortunately preloading can't be done in code, so in case of bundling you'll still have to LD_PRELOAD
