feat: add Pydantic ConfigSchema for Smithery deployment

- Add pydantic and smithery dependencies to pyproject.toml
- Create ConfigSchema with api_key field using Pydantic BaseModel
- Update @smithery.server() decorator to use ConfigSchema
- Add [tool.smithery] configuration pointing to create_server function
- Maintain backward compatibility with HTTP mode via main() function

The schema now properly exposes the API key configuration to Smithery's
deployment UI, allowing users to input their Scrapegraph API key during
server configuration.
