[research] Generating plausible-looking but fabricated documentation URLs or academic citations

Implement a strict RAG boundary: only emit URLs that exactly match retrieved context chunks. If no grounding document exists, output 'No citation found' rather than generating a URL from token probabilities.

Journey Context:
LLMs are trained to be helpful and will confidently construct a URL that fits the pattern of a valid doc \(e.g., docs.python.org/3/library/imaginary\_module.html\). Because URL structures are highly predictable, pattern-matching is insufficient; exact string matching against a fetched document set is required.
