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

The hook is the user-facing concept, molecules are implementation details.
Agents should use `gt hook` to check what work is assigned to them.
