Subject: [PATCH] feat: add Dropdown Menu component

Adds the Dropdown Menu (Reka UI DropdownMenu + COSS styling), wiring up the
previously-placeholder 'Dropdown and Popover' nav entry.

- ui/DropdownMenu/*: DropdownMenu, Trigger, Content (portal + COSS surface
  with inset highlight), Item, Label, Separator, Group, Shortcut
- 2 demos: labelled menu with shortcuts, and an icon menu with grouped items
- Showcase view + route; Home nav 'Dropdown and Popover' (#) -> 'Dropdown Menu'

Verified: type-check, lint, build, and visual check (menu opens, items +
shortcuts render on the COSS surface).
