/**
 * SDK Test Runner — Fixtures
 *
 * Provisions reusable test resources before domains run and tears
 * them down afterward.  Modeled on the ICD test runner's fixture
 * pattern.
 *
 * Fixture resources (all optional — domains degrade gracefully):
 *
 *   providerConfig   Global API config created from the first admin
 *                    config that has at least one embedding model.
 *                    Enables: knowledge.search, model preference tests.
 *
 *   embeddingModel   {model_id, provider_config_id} picked from the
 *                    enabled models list after the config is created.
 *
 *   policies         Policy toggles applied at setup, reverted at
 *                    teardown (e.g. allow_user_personas).
 *
 *   team             Test team (with current user as admin).
 *
 * Access: window.SDKR.fixtures.*
