/**
 * E2E — AgentBridge page smoke tests
 *
 * These tests require the OmniRoute server to be running at http://localhost:20128
 * (or the URL in PLAYWRIGHT_BASE_URL / baseURL in playwright.config.ts).
 *
 * CI behaviour: tests are marked `.skip` unless the env var
 * `RUN_AGENT_BRIDGE_E2E=1` is set, since they require a full server process
 * AND port 443 privileges (or mock). In CI the unit/integration suites provide
 * functional coverage; the E2E layer verifies UI navigation and wiring.
 *
 * To run locally:
 *   RUN_AGENT_BRIDGE_E2E=1 npx playwright test tests/e2e/agent-bridge.spec.ts
