[data] Extend menu-scan to classify food type + kitchen hours (Food note)

[iamjohnnymac]

Extend the menu-scan vision prompt to classify food type + kitchen hours (high-confidence only) -> power a Food/Menu note module ("pub-feed / pizza / burgers", link official menu, NEVER copy menus). Deferred.

Why

Satisfies the adjacent intent of "[venue] menu" without reproducing menus; only ship when high-confidence data exists.

Acceptance

• Food type / kitchen hours captured at high confidence; Food note renders only when present and links out

Effort: M (defer)
