/**
 * Real end-to-end test of v2: host router → Docker container → agent-runner → delivery.
 *
 * 1. Init central DB with agent group + messaging group + wiring
 * 2. Route an inbound message (creates session, writes inbound.db, spawns container)
 * 3. Container runs v2 agent-runner, polls inbound.db, queries Claude, writes outbound.db
 * 4. Poll outbound.db for messages_out response
 *
 * Usage: npx tsx scripts/test-v2-host.ts
