Scope-aware hierarchical memory for ADK agents via OrgMemoryService — wiring it through ADK's service registry with three env vars, plus how retrieval works (hybrid RRF fusion of keyword and vector arms, tier boost, floor-gated boost cascade, autocut, a zero-LLM knowledge graph, relational recall, and answer synthesis). Read when an agent needs memory shared across users/teams/an org rather than p
