[Feature Request] Show a percentage stat in the window's title bar

[ifarbod]

Currently, there's no way to view a project's completion percentage, unless you use the CLI to generate a report, it'd be nice to see it all the time in the GUI!

Possibly with the option to pick which stat to show: matched_functions_percent, matched_code_percent, complete_code_percent (or show all of them at once)

Never thought of that, but it'd be a really useful QoL feature!
