Improve slugify function, add tests, and enhance Makefile

Applied improvements from feature-code-quality branch:
- Refactored slugify() for better readability with inline comments
- Renamed log() parameter *args to *log_args (avoid shadowing built-in)
- Added comprehensive unit tests for slugify function
- Enhanced Makefile with typecheck and test targets
- Updated build target to run type checks and tests before Docker build

All tests pass and type checking succeeds.
