Pull Request Overview

This PR introduces a new generic RAG agent sample that demonstrates multi-source information retrieval combining context grounding indexes, web search, and optional MCP tool integration. The agent uses a LlamaIndex workflow with ReAct reasoning and includes human-in-the-loop feedback capabilities.

Key changes:

• Implementation of a flexible RAG agent with multi-knowledge base support using UiPath Context Grounding
• Integration of Tavily web search for real-time information and optional MCP server connectivity for dynamic tool loading
• Human-in-the-loop workflow with iterative feedback and answer refinement
