Test-infra only (e2e/ is not in the deployed artifact). Refines the
v0.52.0 deployed-env harness:
- retries:2 + on-first-retry trace now meaningful (was dead: retries
defaulted to 0); de-risks timing flakes over the public edge.
- workers:1 — the metadata specs run in order and write real commits;
parallel workers would race on shared state and concurrent bot pushes.
- deployed timeouts bumped (60s/20s) when E2E_TEST_AUTH_SECRET is set.
- dismissCookies forcibly removes any lingering consent-banner node so it
can't intercept catalog-footer checkbox clicks (the recurring flake).
