[Will-Hellinger]

Someone will need to double check this LOL

• Migrate to ruff
• Migrate to uv for docker image
• Fix csh_ldap not working
• Optimizations via small caches

took a look through, though I found it hard to read through all the formatting. Glancing through commits, seemed like there wasn't much in code changes, more in deps and CI?

Have a couple comments

Code looks good, need to run it locally to test

[pikachu0542]

I was able to get it running locally, and it works. However, I cant seem to figure out how to test the mock user functionality, and with no open packets, I cant verify that the main functionality still works as expected.

nit: typically each linter/formatter is run as a separate stage since its easier to tell which one failed

[costowell]

This seems a little overengineered to have an auto format workflow especially since there is a format check part of the linting workflow already. I think it'd be better to let people fix the formatting themselves instead of a github bot committing to their branch automatically.

Can this (and all other cases like this) be an Optional[T]?

Why was this changed? The previous link was valid and this one is to a 404.
