toggle-main-menu and toggle-more-options close over a state atom and
need no external deps. The declared deps (main-menu-open? /
more-options-open?) were unused inside the function bodies, causing
each callback to be reallocated on every toggle — self-reinforcing
churn. Drop the mf/deps calls to make both callbacks stable.
