researchclaw-mcp-tool-interface-design

When wrapping AutoResearchClaw as an MCP server, expose 11 tools: researchclaw_run (async, returns run_id immediately), researchclaw_status, researchclaw_get_output, researchclaw_resume, researchclaw_approve_gate, researchclaw_reject_gate, researchclaw_verify_citations, researchclaw_verify_claims, researchclaw_search_literature, researchclaw_list_runs, researchclaw_cancel. The standalone tools (verify_citations, verify_claims, search_literature) must be usable OUTSIDE the paper pipeline so any Oracle agent can enrich reports with citation integrity and academic sources without triggering a full pipeline run.
