test(e2e/agents): add Playwright config for cloud-agents suite

Targets http://localhost:3000 (Next.js dev server) directly. The agents
UI lives in App Router routes which only render under `next dev`, not
the proxy's static export — separate config skips the proxy globalSetup
that the rest of the suite needs.
