refactor: extract event, spec, and enhancement types to shared package

- Extract EventType and EventCallback to @automaker/types
- Extract SpecOutput and specOutputSchema to @automaker/types
- Extract EnhancementMode and EnhancementExample to @automaker/types
- Update server files to import from shared types
- Reduces server code duplication by ~123 lines
