Update menu api

Editor assessment

The subject `docs: update menu api` names the page generically — the Menu API documentation — but says nothing about what was updated or corrected. The docs type is right, and the menu naming substitutes for a scope. The body squash bullets repeat the subject and add a bare `perf` bullet, which is noise rather than explanation. No footer appears. Hygiene is acceptable. The reader learns only that Menu API documentation changed in some way, not what or why.
