Supervised storage and handler lifecycle for Breeze log capture.

A single Breeze server starts an ephemeral collector when log capture is enabled. Applications running multiple Breeze sessions can instead add this module before those sessions in their own supervision tree:

children = [
  Breeze.Logger.Collector,
  {Breeze.Server, view: MyApp.View, logger: :attach}
]

Use a :rest_for_one or :one_for_all strategy when the Breeze sessions should restart after their shared collector.
