Orchestrate E2E catalog authoring, API or integration execution, Playwright browser execution, and optional HTML reporting under one run-owned Testcontainers lifecycle. Use when the agent must run a complete or multi-lane E2E verification, refresh and execute the scenario catalog, combine backend and browser evidence, or produce one false-green-safe E2E handoff. Do not use for authoring-only, runner-only, browser-only, or render-only requests that one component skill can satisfy directly.
