Increase test coverage

[davidfischer]

This was an AI assisted change purely to increase test coverage and test some edge cases.

• Added an AGENTS.md file for AI code agents to read. Notably tells the AI agent how to run tests and to always run tests during the process.
• Updated pyproject.toml to run formatters on test code
• Only made changes to test code

How

Basically I used Google Antigravity, informed the agent about the current test coverage and how to get the coverage levels. Then I increased the test coverage requirement to 94% and set the agent in a loop to add tests, run the tests and see if the coverage was >94%, and repeat until it is.

After 20 iterations (~1.5-2hrs), it hit the threshold. I had to do a small amount of cleanup to the PR but I have reviewed every line and believe this is a net positive.

Seems like a solid improvement 💯

Not sure the bold is needed?

[davidfischer]

I mostly let AI generate this initially and it added this. Maybe it helps because it wanted it?
