fix-types

Your task

To fix types, do the following.

1. First run the type checker to see what the issues are:

   uv run mypy .
   

2. Group the errors you find in to logical buckets.
3. For each bucket of errors, go through the errors one at a time, tell me the fix you want to apply, and then ask if I have any questions or suggestions before proceeding.
4. Only once I approve, apply the fix and move onto the next error in the bucket.
5. Once you've completed a bucket, ask me if I'd like to move on to the next bucket.

Prefer cast() over type: ignore
