v0.56.0

Changed

• django-ag-ui is floored at 0.70.0 and django-spec-agents at 0.2.0. The
  two move together: 0.70.0 is the transport release that runs on
  django-spec-agents 0.2.0, whose spec toolset serves django-service-specs
  specs on service_specs=; django-ag-ui 0.70.0's changelog lists what that
  changes for a project passing them. Its [spec-tools] extra is gone, which
  this package never named.

Fixed

• A spec tool behind the sidebar is handed the acting request. The
  sidebar's deps replace django-ag-ui's default, which from 0.70 carries the
  run's request in AgentDeps.call_context for the spec toolset, so a project
  passing service_specs= to AdminAgentServer gave a spec callable declaring
  request None where any other mount gave it the request. The admin's
  deps now carry it the same way. A project passing its own deps_factory
  decides its deps and carries it itself, as docs/configuration.md now says
  beside the deps_factory paragraph.
