## Summary
The Omarchy shell (quickshell) crashes with SIGSEGV in the Qt QML engine the moment Wi‑Fi is turned off (or the Wi‑Fi device goes `Unavailable`). The crash is in `QV4::QObjectWrapper::wrap_slowPath` — i.e. the QML engine tries to wrap a `WifiNetwork`/`AccessPoint` QObject that has already been freed (use‑after‑free). The shell auto‑restarts via its watchdog, so the session recovers, but the crash is reproducible on every Wi‑Fi toggle.

## Steps to reproduce
1. Be on Omarchy 4.0.1 with the default shell (`quickshell -n -p /usr/share/omarchy/shell`).
2. Open the Network panel (SUPER+CTRL+W) or just have the bar's network widget live.
3. Toggle Wi‑Fi off (e.g. via the network panel / `rfkill` / NetworkManager `wireless-enabled:off`).
4. quickshell dumps core (SIGSEGV) within the same second.

## Expected
Toggling Wi‑Fi off should update the network panel without crashing the shell.

## Actual
SIGSEGV in the main GUI thread. Journal shows, all within the same second:
- `ERROR quickshell.wifinetwork: WifiNetwork(0x7f8a1fe57640, name="0") is already connected.`
- QML binding‑loop warnings on `/usr/share/omarchy/shell/plugins/panels/network/Panel.qml`: `Binding loop detected for property "height"` and `Binding loop detected for property "wifiNetworkObjects"` (defined at Panel.qml:71).
- `NetworkManager radio-control op="wireless-enabled:off" ...` → device `Unavailable`, active connection removed, cascade of `Access point removed` events (per quickshell debug log).
- `ERROR: Quickshell has crashed under pid 135603` → auto‑restarted.

The faulting instruction (frame #4, `0x7f8a1fe55300`) is in JIT‑compiled QML code in the same heap arena as the `WifiNetwork(0x7f8a1fe57640)` reported "already connected" just before — consistent with a freed QObject still referenced by the `wifiNetworkObjects` binding (flagged in a binding loop) being wrapped after teardown.

## Environment
- Omarchy: 4.0.1-1 (BUILD_ID 4.0.1)
- Quickshell: 0.3.1 (revision , distributed by Arch Linux)
- Qt: 6.11.2 (built against 6.11.2)
- OS: Omarchy (Arch‑like)
- GPU: NVIDIA 10de:1f91 (nvidia-drm)
- Note: `omarchy debug` is not a valid command on 4.0.1 ("Unknown Omarchy command"), so diagnostics below come from systemd-coredump + quickshell's own crash report.

## Crash details
- PID 135603, signal SIGSEGV (si_code SI_TKILL), main thread.

## Workaround
Avoid toggling Wi‑Fi off through the panel until fixed; the shell recovers on its own via auto‑restart in any case.

## Notes
Searched existing issues — many quickshell crashes exist, but none matching this network‑panel `wifiNetworkObjects` / `wrap_slowPath` failure, so filing as new.
