Quality Update - Incremental Implementation

Systematically implement code quality improvements from the review document, making tested, atomic commits for each fix.

Process Overview

1. Read the quality review from docs/quality_review.md
2. Prioritize improvements (start with Quick Wins, then High Priority)
3. Implement fixes incrementally (one logical change at a time)
4. Run tests after each change to ensure nothing breaks
5. Make atomic commits that capture the change and its purpose
6. Update review document to track progress
