v0.17.0

Added

• The stable dispatch surface (SURF-1). The leaves an alternate
  transport builds on are now documented public API, re-exported from the
  top-level package with a semver stability promise — see the new
  Dispatch (stable surface) reference page: resolve_callable_kwargs,
  is_async (shared); run_service, arun_service,
  build_input_serializer, validate_input, resolve_mutation_instance
  (service side); run_selector, arun_selector, is_queryset,
  apply_queryset_shaping (selector side). Previously downstream packages
  (drf-mcp) imported these from private/utils paths, so a within-range
  refactor could break them silently. An import-surface test pins the
  blessed exports.

Removed

• The private _compat package. run_service / arun_service moved
  to services/ and is_async to the package root (all three are part of
  the blessed surface above). Breaking for anything importing
  rest_framework_services._compat.* — in practice only
  drf-mcp ≤0.7, whose dependency cap (<0.17) keeps it on 0.16; its next
  release re-points the imports and widens the pin.

Documentation

• The view-coupled orchestrators (dispatch_mutation_for_spec,
  dispatch_selector_for_spec) are explicitly not part of the stable
  surface — a transport-neutral spec dispatcher is future work that will
  compose the blessed leaves.
