## `LogosDelivery` is the project entry point. It is a pure concentrator: it
## owns exactly one instance of each API layer
##
##   Waku  <-  MessagingClient  <-  ReliableChannelManager
##
## and chains them together (each layer drives the one below it). Every layer
## keeps its own, separate public API — `LogosDelivery` only wires them up and
## drives the shared `new` / `start` / `stop` lifecycle.
