/**
 * Agent registry — tracks agent profiles and per-agent write statistics.
 *
 * Agents are registered via `registerAgent(profile)` which upserts a
 * `agent/<agentId>/profile` entry and initialises a `stats` sibling. Stats
 * are updated by `updateStats()` after every write action and auto-initialised
 * for agents that write without registering first (so stat tracking never
 * silently drops events).
 *
 * Key exports:
 *  - `registerAgent(profile)` — upsert profile + init stats
 *  - `updateStats(agentId, action, confidence)` — increment counters
 *  - `getAgent(agentId)` — fetch profile + stats together
 *  - `whoKnows(entityType, entityId)` — list agents that contributed to an entity
 *  - `listAgents()` — all registered profiles
 *  - `assignToTeam(agentId, teamId, createdBy)` — add MEMBER_OF relationship
