-two public fixtures: a live-like zero-item summary and a stale/rebase-required

-fresh, stale, and missing readiness fixtures. It verifies the status badges,
-readiness/rerun decision, artifact window, age, reason, and source-of-truth copy
-for canary promotion readiness. The canonical fixture/browser script is
-`examples/dashboard-promotion-readiness-browser-smoke.mjs`; use the npm script
-above instead of calling ad hoc duplicate filenames.

 before browser checks, so the structured `gate_state`, `can_promote`, and
 `should_warn` contract is covered even when browser smokes are skipped.
