v4.4.0

UI modernization release — redesigned navigation, 28 reusable UI
components, full i18n compliance, accessibility infrastructure, and a
unified visual language across every screen.

• New 5-tab navigation — Home, Games, Files, Console, Tasks. The old
  40-item sidebar is now a clean tab rail (desktop) and bottom nav
  (mobile), with secondary destinations in a "More" drawer.
• Home dashboard — new landing page with console status, quick
  actions, recent activity, storage, and telemetry widgets.
• 28 UI component primitives — Spinner, Badge, ErrorCard, EmptyState,
  Callout, Card, Tabs, Tooltip, Drawer, Sheet, Toaster, LiveRegion,
  SkipNav, and more. All screens now use a shared design system instead
  of ad-hoc markup.
• Unified loading & error states — every screen's spinner and error
  display now uses the centralized Spinner and ErrorCard components
  for consistent visual feedback and screen-reader announcements.
• Full i18n compliance — all hardcoded UI strings migrated to the
  translation system. Zero lint errors from the no-untranslated-jsx
  rule.
• Accessibility infrastructure — WCAG 2.2 AA groundwork: skip-nav,
  live regions, reduced-motion support, 44px touch targets, keyboard
  navigation, and focus management.
• Mobile groundwork — pull-to-refresh, bottom tab nav, back-stack
  support, and haptic feedback hooks.
• Engine fix — cheats.rs compile fix for Android (NDK rustc type
  inference).
