/**
 * useOverlays Hook
 *
 * Manages all boolean overlay/dialog visibility states in App.tsx.
 * Returns individual state pairs (preserving existing variable names)
 * plus a computed `isAnyOverlayOpen` for inputEnabled calculation.
 *
 * Internally backed by a single useReducer + state record. The previous
 * implementation used 33 separate useState pairs plus a 33-term OR chain
 * (and matching 33-item deps array) that had to be touched every time a
 * new overlay was added. The reducer shape makes adding an overlay a
 * one-line change: add the key to OVERLAY_KEYS and the surface,
 * isAnyOverlayOpen, and setter map all pick it up automatically.
 *
 * Public return shape is stable: every `showX` and `setShowX` pair still
 * exists by name so that OverlayContext consumers don't have to change.
 *
 * @since v2.4.13 (reducer-backed since v2.11.5)
