/**
 * Runtime Host Integration — End-to-End Tests
 *
 * Validates the full lifecycle for runtime-host integrations (eBPF Agent):
 *   1. Fixture compose health
 *   2. Direct endpoint probe
 *   3. Connector plugin API (create, test-connection, health, delete)
 *   4. UI: Runtimes / Hosts tab shows created integration
 *
 * Prerequisites:
 *   - Main Stella Ops stack running
 *   - docker-compose.integration-fixtures.yml (includes runtime-host-fixture)
