Move build system to UV, add vscode debugger/test ui, add python 3.13 build/test target

[nateinaction]

Hey Lynn,

I playfully (🪂) worked my way toward debugging issue #187. To start that journey I wanted to update some of the developer tooling to help me get to debugging a little quicker. I also needed to update the CI system to get builds passing since some of the action images had been deprecated and removed. What do you think?

• Moved to using UV for python environment management

• Updated contributing readme with new uv based commands

• A teensy weensy code change in badge_gen.py to satisfy mypy

• Another teensy weensy code change in badge_gen.py to prevent an OSError from ruining the day

  E   OSError: no library called "cairo-2" was found
  E   no library called "cairo" was found
  E   no library called "libcairo-2" was found
  

• Added testing for python 3.13 and set that as the latest version

• Updated all ci dependencies because ci was broken

• Added support for running tests in vscode ui

• Added support for running the debugger in vscode

• Improved error message when interrogate encounters a syntax error in a codebase

Before

After

Have you tested this? If so, how?

All tests running in CI and I have tested all contributor doc commands locally.

Happy Monday @econchick! I've updated the PR to use the uv build backend which is now stable.
