feat(advisor): Clarity-Gate orchestration in route.ts (consumes /retrieve)

Completes the advisor stack (FE + orchestration; /retrieve is SDK/RAG-owned). The route
now returns the FE contract instead of a text stream:
- retrieveFull() calls /retrieve with {query, context}; consumes clarity/evidence/
  visual_evidence/footnotes (exact shape per board 2026-07-01 12:25).
- mode-routing (resolveMode): clarify unless a context was chosen and /retrieve's
  clarity.mode says so. clarify -> L1 general answer (completeAdvisorAnswer, ungrounded,
  no sources). answer -> L2 answer over numbered evidence with [n] markers.
- citations generated here ([n] -> nth evidence unit); footnotes remapped; evidence /
  visual_evidence passed through.
- advisor-llm: non-streaming completeAdvisorAnswer(). Pure mappings in retrieve-mapping.ts
  (+ tests). Removed the dead v2 evidence.ts/evidence-adapter (RegulationRef moved to
  regulation-display). controls-augmentation kept (tested; re-integrable later).

NOT deployed: joint deploy with the SDK /retrieve endpoint (deploy-coupling). tsc clean,
25 vitest (mapping/clarify/answer/markdown/registry/rag), check-loc 0.
