recruiter-triage v3: Perks & Office Life section + cache-first deep_research

- claude-agent-service bumped to f764fef6 (agent system prompt adds
  the Perks block: food/health/pension/equity/PTO/parental/equipment/
  learning/wellness/amenities/commuter). 1200-word cap.
- recruiter-responder bumped to 38a2cdaa (cache-first deep_research:
  serves cached payload if fetched_at + ttl_seconds > now; cache
  writes upsert; new force flag bypasses).

Verified end-to-end: deep_research on Datadog now returns full Perks
section (~220s, $0.60, 23 turns). Earlier 500 fixed (was
uq_research_company_tier dup-key on re-run).
