Jobs extensions need to know when a container finishes so they can
record the outcome of a run.
Add org.mobyproject.extension.container.state.v0.
Its Wait call returns once the container reaches a requested status,
and Watch streams every status change until the container is removed.

Add org.mobyproject.daemon.monolith.v0 to expose daemon capabilities
as extension points.
It is a temporary bridge until the daemon is split into independent
extensions.
