Remove AI code slop

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

This includes:

• •Extra comments that a human wouldn't add or is 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
• •Any other style that is inconsistent with the file
• •Unnecessary type annotations on obvious types
• •Over-verbose variable names
• •Redundant null checks when TypeScript already guarantees non-null
• •Console.log statements left for debugging
• •Commented-out code blocks
