macos: Option to round quick terminal window corners

[colepeters]

Thanks so much for all your work on Ghostty! 😊

On macOS, when using the center option for quick-terminal-position, the use of sharp corners feels somewhat out of place with the rest of macOS’ windowing system. Could we have an option to use rounded corners on quick terminal windows?

This sounds reasonable and probably something we don't need a config for and should just do. The question is whether we can do this at all. I think the sharp corners come from the type of window it is that lets it float above all the others (i.e. it's a macOS native thing).

Gotcha! FWIW I'd be super happy if it wasn't a config option either, and instead just baked in. I'm totally clueless about macOS native development, but it seems like apps like Raycast and iTerm are able to render floating windows with rounded corners, so perhaps there's some prior art? But again, totally not here to claim any sort of knowledge on this ;)

Thanks so much for the consideration!

wezterm has something similar

I created a draft pr which brings back the titlebar (hidden) to achieve a native rounding.
I made it into a quick-terminal-decoration option to match the main window convention.
The default behavior enables this option for the center position only.
Also fixed the animation issue that the titlebar was creating (mentionned by mitchell somewhere)
