Simple Dropdown Menu

A click-triggered menu that composes the dropdown primitives and shares CommonMenuItem, groups, labels, separators and delete actions with context menus and drawers. Inline confirmation keeps its label width and resets on menu close. Command/Control-click skips inline or ordinary dialog confirmation, but never a required confirmationText. mobileView="bottom-drawer" adapts the same content on touch screens. Use it for ordinary action or account menus to avoid rebuilding closing, link and mobile behavior; use the dropdown-menu primitive for custom composition.
