Before we start...:

• I checked the documentation and didn't find this feature
• I checked to make sure that this feature has not already been requested

Branch/Commit:

In the main branch.

Problem:

Please include a detailed description of the problem this feature would solve.

As a skunk user
I want to see the progress of my skunk score average over time
So that I can track whether my project is getting better or worse ("tech debt"-wise)

Mockups:

Not really a mockup but you can see a slide where I show this idea over here: https://speakerdeck.com/etagwerker/escaping-the-tar-pit-at-socrates?slide=139

Notes:

We will need a new page that will be a "project view" (this depends on #30) which will have to live here: https://skunk.fastruby.io/projects/:project_name

I will abide by the [code of conduct] (https://github.com/fastruby/skunk.fyi/blob/main/CODE_OF_CONDUCT.md)
