feat: Implement Creative-to-Ops Conversion (Creativity Engineering)

Implements issue #20: Creative-to-Ops Conversion system.

New features:
- Creativity Engineering project: unlocks conversion between Creativity and Ops
- Creative Catalyst project: boosts conversion efficiency by 50%
- Inspiration Engine project: automated creativity synthesis from fleet harmony
- Creative -> Ops button: converts creativity into ops + knowledge
- Ops -> Creative button: converts ops back into creativity (bidirectional)
- Harmony bonus: high harmony (>60) improves conversion yields
- New creativityBoost multiplier tracked in save/load
- Education fact about Creativity Engineering

The system creates a meaningful resource loop: creativity (generated by Bilbo
and idle ops) can now be channeled into operational infrastructure, while ops
can feed back into creativity. High harmony amplifies the conversion,
rewarding players who maintain fleet health.
