Add a meilisearch service to the dev docker-compose (port 7700, persistent volume)
and MEILI_URL/MEILI_KEY (+ IIOS_CRED_KEY, IIOS_MEDIA_GC_INTERVAL_MS) to .env.example.
Add deploy/meilisearch.yaml — a ready-to-apply k8s Deployment/Service/PVC/Secret for
the ArgoCD prod stack (copy into k8s-pods/services/iios/), with wiring notes for the
iios-service env (MEILI_URL=http://meilisearch:7700, MEILI_KEY from the secret).

Adds an opt-in RedisIoAdapter (wired in main.ts when REDIS_URL is set) so
socket.io room emits fan out across instances via Redis pub/sub — a client on
replica B now receives messages emitted by replica A. Without REDIS_URL the
in-memory adapter is kept (single-instance dev unchanged). Adds redis to
docker-compose, REDIS_URL to the env contract, and smoke-realtime-cluster.mjs
which proves cross-instance delivery fails without Redis and passes with it.
Delivery is at-least-once at N>1; clients dedupe by message id (documented).
