Add Constitutional AI framework to Chapter 14

What

Anthropic's Constitutional AI approach achieved 95.6% jailbreak resistance through explicit principles and transparency mechanisms. This is concrete, measurable evidence that AI safety isn't purely theoretical — working approaches exist.

Why

Chapter 14 discusses AI risk. Having a concrete, quantified safety approach strengthens the book's argument that active management works better than prevention. It also counters the narrative that alignment is unsolved.

How

In Chapter 14's section on practical approaches to AI risk, add Constitutional AI as evidence that alignment work produces real, measurable results. Frame as supporting the book's argument: manage and develop with understanding, don't ban and restrict from ignorance.

Impact

Provides concrete evidence for the "management beats prevention" argument. Differentiates informed development from reckless deployment.
