Add a UI-Lab-only (mode === "ui", dead-code-eliminated from real builds) URL override for the What's New modal: ?changelog=unreleased shows the in-progress notes before they ship, ?changelog=small serves a synthetic hotfix-sized entry to exercise the compact layout (including a no-lead bullet), and ?changelog=<version> previews any released entry. Documented in docs/ui-lab.md alongside the ?scenario= table.
