Faster, cheaper research runs

• OpenAlex exact searches (openalex_search_works, citations, references, authors, venues) now return at most the tool's limit (default 5, max 20) instead of 50-100 full records; an explicit max_records is capped at 50. In live /lit runs these results were 100-240 KB per call and drove most of the multi-million-token usage.
• The researcher and verifier subagents run in the background by default, where they get Feynman's web and literature tools. Foreground launches of these agents failed and had to be retried.
• alpha_ask_paper now states it takes arXiv and alphaXiv papers only, and points DOI-only papers to fetch_content or Europe PMC full text.
