Feature Request

Is your feature request related to a problem? Please describe.
Currently, API documentation needs to be maintained separately from code.

Describe the solution you'd like
Add automatic API documentation generation:

• Parse TypeScript types
• Generate OpenAPI/Swagger specs
• Create interactive documentation
• Support for custom annotations
• Export to various formats

Describe alternatives you've considered

• Integrate with existing documentation tools
• Add as a build step
• Create a separate documentation service

Additional context
This would ensure API documentation stays up-to-date with code changes.
