v0.11.0

Changed (breaking)

• MCPServer.urls / .async_urls now return a namespaced
  (patterns, app_name, namespace) triple — the shape path() mounts directly,
  the admin.site.urls idiom, aligning with django-ag-ui's AGUIServer.urls
  (the MOUNT cross-package symmetry). Mount without include():

  # before
  urlpatterns = [path("mcp/", include(server.urls))]
  # after
  urlpatterns = [path("mcp/", server.urls)]

  The endpoint URL names are now namespaced and unqualified within the
  namespace: mcp-endpoint → mcp:endpoint, mcp-protected-resource-metadata →
  mcp:protected-resource-metadata (default namespace "mcp"; override with the
  new MCPServer(url_namespace="…")). Update any reverse() / {% url %} calls
  and switch the *server.urls splat form to path("mcp/", server.urls).
