feat: add Claude mode support with conditional Express server initialization

- Modify index.ts to conditionally start Express server based on PROCESSOR_TYPE
- Add logic to skip server initialization when in Claude mode
- Update file comments to reflect new conditional server startup behavior
- Log informative message when running in Claude mode
