Improve responsiveness and feedback for slow commands (`gen`/`generate` and `start`)

[Chungzter]

Currently, these commands don’t feel very responsive. When invoked, the program may appear to “hang” while waiting for results, which can confuse users and make the experience feel unpolished. To ensure the user that the tool isn't hanging, there are several things we can do ( exact approach to be determined):

• Provide user feedback while waiting:
  • A simple warning: e.g., “This may take a few seconds…”
  • A lightweight spinner or animated three-dot ellipsis (... cycling effect).
  • Other minimal, non-intrusive progress indicators.
    -Ensure responsiveness without blocking user input (if feasible).

Improved feedback will make the CLI feel more alive and user-friendly. Even small visual cues reduce perceived waiting time and improve the overall user experience.

Also, if we solve #15 We wont need to do this for the generate command.

There's a cool pattern used by some CLIs to show they're "loading": they use use Braille characters and cycle through certain ones to show a cool circling pattern. I think We'll go with that.

can i take this on?

Hi @bored-arvi . Sure!

Make a function inside output.py that shows a text with the loading braille characters. Maybe call it print_loading()? Up to you though if you think of something better for the name.

From there though, you should be able to do something like multithreading the call to the printer. We should also pass a done boolean flag to the print_loading ( or whatever it's name is) to check for the flag and exit once it's set to True. We'll run the program and then set the flag. Finally printing the corresponding message.

By the way, I don’t think I’ve said this yet, thanks a lot for taking an interest in the project and contributing. I checked out your fork earlier and went through your commits, including the unmerged ones. Great job testing your changes! I really appreciate you help proof-testing the program and contributing code.
