feat(advisor): Authority Router — Advisor collection-agnostisch, KB-2026.1-Gewinn im Produktpfad

Der Advisor fan-outete bisher selbst ueber eine feste Liste expliziter Collections
(advisor-rag.ts) und umging damit das #61-Scope-Routing (das nur den Default-Pfad
routet) → der gemessene +28-Retrieval-Gewinn (CB-100: 53→81, 0 Regr) kam nie beim
Antwort-LLM an. Dieser Router zieht den Fan-out in die Retriever-Schicht:

- SDK: LegalRAGClient.Retrieve() + POST /sdk/v1/rag/retrieve {query, top_k} —
  fan-outet server-seitig ueber die Broad-Authority-Base + die KB-2026.1-Slice bei
  inKBScope, merge+dedup, sortiert nach Authority-Score (rerankByAuthority je
  Collection), top-K. Index-Warmup vor dem nebenlaeufigen Fan-out (Map-Race-frei).
  Per-Env via RAG_ROUTER_COLLECTIONS.
- admin: advisor-rag.ts ruft EINMAL /retrieve statt 6-fach expliziter Collections.
  Advisor ist collection-agnostisch (Vertrag Compiler→Collections→Retriever→Advisor);
  COMPLIANCE_COLLECTIONS/searchCollection entfernt.

Validierung: Go-Unit (Router-Selektion, dedup); e2e gegen dev-Qdrant (echter
Retrieve(), CB-100-Stichprobe stride 5): OLD-hit 11/20 → NEW-hit 15/20, GAIN 4
(alle DS-Guidance), REGR 0 — reproduziert den +28/0-Regr durch den Produktionscode.
TS-Tests auf den Single-/retrieve-Call angepasst.
