[clean code] Code smells workshop

This meetup follows the Reddit tutorial "How to Find the Stinky Parts of Your Code" and uses its catalog of code smells as a structured learning exercise.

For the first 3 hours, participants work through a series of short rounds:

• Read a code smell individually (10 minutes)
• One participant is selected at random
• The selected participant explains the smell to the group (5 minutes)

All participants must be willing to present the code smell they have just read, as anyone may be selected during a round.

In the final hour, we will collaboratively build a Claude Code review command that uses code smells as review criteria to identify maintainability and design issues in real codebases.
