I was unable to find a specific issue or PR that mentions this.

As Linux installations always use built-in prompts and ignore the `Use
System Prompts` setting (as far as I'm aware) all users using Zed (with
client-side decorations) are affected. The darkened prompt backdrop was
drawn across the full window boundary, including the transparent
decoration/shadow inset, causing it to overlap.

This PR fixes the backdrop to respect the client-side decoration inset
and only applies rounded corners on non-tiled edges. Tiled edges remain
flush, matching the rest of the client-side window decoration behavior.
I've verified it works on Wayland, X11 and causes no regressions on
macOS or Windows (with `Use System Prompts` off).

Notice the screenshots below on a white background showing the before
and after, where the faint overlap is shown broken and fixed (sorry if
you have to squint).

Release Notes:

- Fixed prompt darkened backdrop/background rendering outside
client-decorated window boundaries on Linux.
