MenuList: FocusZone not wired for react-native-windows ('windows'), so menu items are Tab-only (no arrow-key roving focus)

Summary

@fluentui-react-native/menu's MenuList only wraps its content in a FocusZone on
macos and win32, not on windows (react-native-windows / Fabric). On windows
the focusZone slot falls back to a plain View, so menu items are reachable only via
Tab — Up/Down/Home/End arrow-key roving focus does not work. This is an accessibility
gap (keyboard + screen-reader users expect arrow-key navigation within a menu).

Location

packages/menu/src/MenuList/MenuList.tsx:

const shouldHaveFocusZone = ['macos', 'win32'].includes(Platform.OS as string);
// ...
slots: { ..., focusZone: shouldHaveFocusZone ? FocusZone : View }

'windows' is not in the list.

Reproduction

Environment: a react-native-windows (New Architecture / Fabric) app,
Platform.OS === 'windows'.

Minimal component:

import { Menu, MenuTrigger, MenuList, MenuItem } from '@fluentui-react-native/menu';
import { Button } from '@fluentui-react-native/button';

export const Repro = () => (
  <Menu>
    <MenuTrigger>
      <Button>Open menu</Button>
    </MenuTrigger>
    <MenuList>
      <MenuItem>Item 1</MenuItem>
      <MenuItem>Item 2</MenuItem>
      <MenuItem>Item 3</MenuItem>
    </MenuList> </Menu>
);

Steps:

1. Run the app on  windows  (RNW / Fabric).
2. Open the menu and move keyboard focus onto the first  MenuItem .
3. Press the Down arrow (also try Up / Home / End).

Expected: focus moves between menu items (Down → Item 2 → Item 3; Up reverses;
Home/End jump to first/last) — the arrow-key roving focus you get on  win32 / macos .

Actual: arrow keys do nothing; items are reachable only by repeatedly pressing Tab.
On  windows ,  MenuList  renders its  focusZone  slot as a plain  View 
( shouldHaveFocusZone = ['macos','win32']  in  packages/menu/src/MenuList/MenuList.tsx ),
so there is no container-level FocusZone to intercept the arrow keys.

Cross-check: the same code on  win32  (or  macos ) navigates correctly with arrows,
confirming the difference is the missing  'windows'  FocusZone wiring, not the menu markup.


### Actual behavior

On  windows ,  focusZone  falls back to  View ; menu items are Tab-only, arrows do nothing.

### Expected behavior

On  windows  (RNW/Fabric),  MenuList  provides container-level arrow-key roving focus
(Up/Down/Home/End), consistent with  win32 / macos .
