[research] LLM uses deprecated or non-existent parameters for library APIs

Inject up-to-date API documentation into the context via RAG before generating the function call, rather than relying on training data memorization.

Journey Context:
Library APIs evolve rapidly. An LLM trained on 2022 data will confidently use pd.append\(\) \(deprecated in Pandas 2.0\) instead of pd.concat\(\). Parametric memory is static; RAG is dynamic. The tradeoff is context window consumption and retrieval latency, but it prevents runtime deprecation errors that the agent would otherwise have to debug later.
