Remove AI code slop

Check the diff against the base branch and remove AI-generated slop introduced in the branch.

Focus Areas

• Extra comments that are unnecessary
• Defensive checks or try/catch blocks or similar guardrails that are abnormal for trusted code paths
• Casts to any (or similar language-specific overly broad type) used only to bypass type issues
• Deeply nested code that should be simplified with early returns

Guardrails

• Keep behavior unchanged unless fixing a clear bug.
• Prefer minimal, focused edits over broad rewrites.
• Keep the final summary concise (1-3 sentences).
