plex gains a broker-bound tools/events runtime container (mesh-runtime-plex)
alongside its server, and a never-throwing plex_reachable health probe. redis and
postgres subscribe to their own lifecycle events in index.ts but declared no
consumes — so the substrate never made the queue the runtime binds and it crashed
on start (404). Declare the consume, as ADR 0046 requires. Proven end-to-end in the
mesh-lab: assigned-plex and assigned-redis both green.
