126-134: New section improves README structure and visibility of production frameworks.

The new "Technologies and Frameworks" section is well-placed after Key Features and provides clear, concise descriptions of each framework. The PydanticAI description effectively communicates its unique value proposition (type safety, structured outputs, Pydantic integration) within the RAG context.

Minor note: The PydanticAI entry is noticeably longer than the others (LangChain, LlamaIndex, Contextual AI). Consider either expanding the others slightly for visual balance or trimming PydanticAI's description to 2-3 sentences max, depending on whether you want to emphasize PydanticAI's prominence in this repository.

605-605: Keywords updated appropriately.

The addition of "PydanticAI" and "Agent Frameworks" to the keywords improves discoverability and aligns well with the new section and the PR objectives. The keywords now accurately reflect the repository's scope.
