macOS dark window theme does not have correct border style

[clo4]

Dark theme windows are supposed to have a lighter, thicker border around them (see iTerm below)

Ghosttty had this in dark mode until recently. When starting the app, you can briefly see the correct colour border, then it sets itself to the light-mode appearance.

This issue is reproducible for me with and without configuration. Changing window-theme to auto or dark made no difference in my testing.

I noticed the same after updating to version 1.0.1, either setting macos-titlebar-style = native or background-opacity = 0.999 fixed it for me.

This should be fixed in 1.0.2 by #4308. 👍
