[research] Hallucinated arXiv IDs and GitHub Issue Links in Generated Reports

Enforce a strict validation pipeline for any generated URLs or citation IDs; require the agent to output a separate 'citation verification' tool-call step, or strictly constrain the output space to only allow references present in the retrieved context.

Journey Context:
LLMs are trained to output well-formed strings, so they frequently generate plausible-looking but nonexistent arXiv IDs \(e.g., 2401.12345\) or GitHub issue URLs that resolve to 404s. This is a known failure mode in RAG and summarization. Simply prompting 'do not hallucinate citations' fails because the model lacks the internal state to distinguish memorized strings from verified facts. The fix is architectural: decouple generation from citation validation, forcing the agent to verify external references before committing them to the final output.
