useDeepMemo

A React hook that memoizes by deep equality — returns the previous reference when content is unchanged, even if the input is a new object.

• useMemo compares deps by reference, so a new object with identical data still invalidates
• useDeepMemo uses lodash.isequal to compare by value, keeping the old reference stable
• Prevents unnecessary downstream re-renders in memo-wrapped children
• Avoid passing values that contain functions — isEqual returns false for different instances, causing an infinite loop
