Remove AI Code Slop

Check the diff against main and remove all AI-generated slop introduced in this branch.

What to Remove

• Extra comments that a human wouldn't add or are inconsistent with the rest of the file
• Extra defensive checks or try/catch blocks that are abnormal for that area of the codebase (especially if called by trusted/validated codepaths)
• Casts to any to get around type issues
• Inline imports in Python (move to top of file with other imports)
• Any other style that is inconsistent with the file

Process

1. Get the diff against main: git diff main...HEAD
2. Review each changed file for slop patterns
3. Remove identified slop while preserving legitimate changes
4. Report a 1-3 sentence summary of what was changed
