"""Onboarding Advisor endpoint — exposes the existing Smart Onboarding Advisor at runtime.

This adds NO new reasoning logic. It exposes the already-built, tested orchestration (Signal Producers
-> Normalizer -> Silent Knowledge Pass -> Advisor) through one runtime endpoint. No DB, no persistence.

  POST /onboarding/advisor-start  — (company + certs + target + scanner findings) -> advisory payload
  GET  /onboarding/targets        — the supported target ids
