Fix the replay of a memoized search filter

Your app's search list stopped narrowing as users typed. A recent change wrapped the filter in useMemo with the dependency list [rows], but the callback also reads search. useMemo caches a computed value and recomputes it only when a value in its dependency list changes. For the postmortem, the team wants a replay of the row count on screen at each render.

An assistant wrote filtered_counts(rows, searches, deps_include_search). It is in the editor. It has a bug. Find it and fix it.

Input and output:

• rows: the row names, as strings. They stay the same on every render.
• searches: the search box value on each render, in render order.
• deps_include_search: true when the dependency list is [rows, search], false when it is [rows].
• Return a list of integers: the visible row count after each render, in render order.

Rules the tests check:

• A row is visible when the search term appears anywhere inside its name. The check is a plain substring match and is case sensitive. An empty term matches every row.
• Count every visible row, duplicates included.
• The memo always computes on the first render.
• With search in the dependency list, the memo recomputes on every render.
• Without it, the only dependency never changes. Every later render shows the count from the first render, whatever that count was.
• No searches returns an empty list. No rows gives a count of 0 on every render.
