Arc window becomes unmanaged after fullscreen

After fullscreen is closed the Arc window becomes unmanaged. Window parameters don't seem to be updated after fullscreen is closed. This is both for fullscreening in youtube videos, and fullscreening the app itself. This behavior seems to be only with Arc, as other windows are still managed after fullscreen is closed.

Before fullscreen:
```
{
...
"app":"Arc",
...
"split-child":"second_child",
"stack-index":0,
"can-move":true,
"can-resize":true,
"has-focus":true,
"has-shadow":true,
"has-parent-zoom":false,
"has-fullscreen-zoom":false,
"has-ax-reference":true,
"is-native-fullscreen":false,
...
}
```
After fullscreen is opened and closed:
```
{
...
"app":"Arc",
...
"split-child":"none",
"stack-index":0,
"can-move":false,
"can-resize":true,
"has-focus":true,
"has-shadow":true,
"has-parent-zoom":false,
"has-fullscreen-zoom":false,
"has-ax-reference":true,
"is-native-fullscreen":true,
...
}
```

Reproduce the issue on yabai v7.1.11 with macOS 15.3.2, testing both YouTube fullscreen and app fullscreen in Arc. Compare the window parameters before fullscreen and after it closes, especially split-child, can-move, and is-native-fullscreen. Done means Arc returns to its managed state like other windows.
