Built an interactive edition of Ch. 3 — live code + chapter-grounded tutor

[ling-k]

Hi Professor Downey,

I built an interactive edition of Chapter 3 of Think Python: live Python execution in the exercise blocks and an AI tutor grounded in the chapter.

No ask — just thought you'd want to see it. Happy to take it down or change anything if something's off. More chapters in progress.
