feat: add virtues and second shadows to all archetypes
Each archetype now has the full Jungian triad:
- Virtue: the unique contribution (what makes it worth including)
- Shadow 1: primary dysfunction (strength pushed too far)
- Shadow 2: complementary dysfunction (different failure mode)
Virtues: Contextual Clarity, Decisive Framing, Execution Discipline,
Threat Intuition, Assumption Surfacing, Adversarial Creativity,
Maintainability Judgment.
New shadows: Catalog Fetish, Over-Architect, Scope Creep, Gatekeeper,
Whataboutist, Scope Escape, Philosopher.
