Distribute as a MacOS app

### Describe the feature you'd like

I guess many people would be happy with an easy "running on laptop when I use it" deployment, to archive our daily browsing, it would be nice to be able to package this as an app, with the server running in the background, and a minimal settings pane UI

### Describe the benefits this would bring to existing Hoarder users

Increase the user base

### Can the goal of this request already be achieved via other means?

Have a script for people to self-deploy using brew

### Have you searched for an existing open/closed issue?

- [x] I have searched for existing issues and none cover my fundamental request

### Additional context

_No response_

Start by reviewing the existing self-deployment approach and the brew-based script mentioned in the issue. Define the scope for a macOS app that runs the server in the background and provides a minimal settings pane; the issue does not identify files, tests, or an entry point.
