feat: Barnevernet Analyzer — document analysis + partisan RAG brief
7-step agent pipeline: document classification, party extraction, timeline extraction, corpus RAG (child_welfare/echr/family_core/bufdir_guidance), and synthesis using the user's chosen engine (including dbn-legal-agent). Progressive NDJSON streaming renders doc_meta, parties, and timeline cards before the final advocacy brief and procedural red flags arrive. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
