Update all prompts to use gt hook instead of gt mol status

- Role templates (crew, polecat, mayor, deacon, witness, refinery)
- prime.go startup protocol messages
- Documentation (propulsion, reference, molecules, wisp architecture)
- Session hints and sling prompts
- Formula template instructions
- CLAUDE.md
