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

Inject current API documentation into the context window via RAG rather than relying on parametric knowledge; explicitly tag API versions in system prompts.

Journey Context:
Parametric memory is frozen at training cutoff. APIs change rapidly, deprecating old parameters or adding required new ones. An LLM might invent plausible but invalid arguments. Eval benchmarks show high error rates on unseen or updated API specs without grounding.
