[Feature Request] Add granular mouse control options to disable click-selection while preserving scroll

Bug Description
Split mouse controls: allow disabling click-to-select in menus while keeping scroll

The recent change "Added mouse click support to select menus" makes interactive menus selectable by mouse click. I find the click-to-select behavior disruptive, but I want to keep mouse-wheel scrolling and auto-scroll, which I rely on.

Right now this is all-or-nothing: CLAUDE_CODE_DISABLE_MOUSE=1 disables click selection but also kills scroll-wheel support, so there's no way to keep one without the other.

Request: a granular toggle to control mouse features independently — e.g. a settings.json option like menuClickSelectEnabled: false (or separate mouse.scroll / mouse.click flags) so users can disable menu click-selection while preserving scroll.
