refactor: Update local RAG agent to use AgentOS and enhance knowledge management

- Replaced PDFUrlKnowledgeBase with Knowledge class for improved document management.
- Updated to use AgentOS for the application interface instead of Playground.
- Adjusted README to reflect changes in the interface and knowledge base loading process.
- Specified minimum version for the 'agno' package in requirements.txt.

 ## 🦙 Local RAG Agent with Llama 3.2
-This application implements a Retrieval-Augmented Generation (RAG) system using Llama 3.2 via Ollama, with Qdrant as the vector database.
+This application implements a Retrieval-Augmented Generation (RAG) system using Llama 3.2 via Ollama, with Qdrant as the vector database. Built with Agno v2.0.
 
 
 ### Features
 - Fully local RAG implementation
 - Powered by Llama 3.2 through Ollama
 - Vector search using Qdrant
-- Interactive playground interface
+- Interactive AgentOS interface
 - No external API dependencies
+- Uses Agno v2.0 Knowledge class for document management
 
 ### How to get Started?

+### Note
+- The knowledge base loads a Thai Recipes PDF on the first run. You can comment out the `knowledge_base.add_content()` line after the first run to avoid reloading.
+- The AgentOS interface provides a web-based UI for interacting with your agent.
