Create complete agent with all components

Creates a complete agent configuration in a single atomic operation, including:

• Bot tools configuration and setup
• Document management and knowledge base setup
• Flow metadata and settings
• Front rail node configuration (input validation and filtering)
• Agent node configuration (main processing logic with LLM and tools)
• Back rail node configuration (output validation and filtering)

This endpoint provides a streamlined way to deploy a full workflow without requiring
separate API calls to create individual components. The entire agent is created
atomically, ensuring consistency and reducing the complexity of agent deployment.

Use this endpoint when you want to create a complete, production-ready agent in
a single operation. For more granular control or when working with existing
components, use the standard agent creation endpoint instead.
