Add ability to restore Cinny's window size and position

[Neved4]

Description

Enables Cinny on macOS to restore its window state from past sessions, using Tauri's window-state.

Fixes #326 #125

Note that v2 isn’t used to prevent conflicts with gtk-3. We might switch to v2 later, but for now we’re sticking with v1 to avoid breaking issues.

Hi, Sorry this took so long.

I tried to build the app locally with these changes and it failed to build.

@kfiven The issue was introduced by f5bf0d3.

Seems we just need to run .run(context) once at the end.

@kfiven Looks fixed now, give it a try and let me know.

For the record I had to disable code format on save and auto-formatting to avoid introducing style changes.

Would you be open to using rustfmt moving forward?
