Cache for repo configs

[Keyrxng]

It's kinda annoying that the kernel must fetch from both config locations on every request and more often than not only one is needed.

Cons:

• unnecessary use of rate limit
• clogs up the terminal

Solution:

• Could be solved with a KV or in memory cache
• After n requests we re-fetch from the repo just in case
• clean terminal and less rate limit used

Do you think this would be a good thing to implement @whilefoo?

We need to minimize the use of KV and rely more on the GitHub API because we have tighter limits on the Cloudflare side.
