Add an UI

[guumaster]

I'm thinking on adding a simple UI. Maybe some Vue frontend and a web server to perform the updates.

Or maybe something more like k9s

Not sure if this should be splitted to a separate binary and keep it separate from core functionality.

I can help with the frontend: Vue, TailwindCSS.

Yeah, an ui similar to 'vue ui' would be great 👍️
