Add Cmd+Arrow tab navigation in panel

[robinebers]

Description

Add Cmd+Up / Cmd+Down navigation for the open panel so the user can switch between Home and enabled provider tabs without reordering anything.
The shortcut works immediately after opening from either the tray icon or the global shortcut because the panel now reclaims focus when it becomes visible.
The cycle wraps at the ends and skips Settings, and the change is covered with focused panel and app regression tests.

Note

Low Risk
Mostly adds client-side keyboard/focus handling with comprehensive tests; low risk aside from potential UX regressions from globally listening to keydown and changing focus behavior.

Overview
Adds Cmd+ArrowUp/ArrowDown keyboard navigation to cycle the panel sidebar between home and provider views (wrapping at ends), while skipping settings and ignoring key events originating from editable elements.

Ensures the shortcut works immediately after the panel is shown by making the panel container focusable (tabIndex={-1}) and auto-focusing it on window focus/visibility regain and after tray navigation/about events. Updates and expands hook/app tests to cover focus behavior and view-cycling edge cases.

• New Features

  • Cmd+Up/Down cycles through Home and enabled provider tabs; wraps at ends and skips Settings.
  • Auto-focus on window focus and visibility change, and after tray navigation/about; AppShell container is focusable (tabIndex={-1}).
  • Shortcut is ignored when typing in inputs or contenteditable areas; tests added for navigation, focus, and editable targets.

• Refactors

  • Consolidated focus logic into a single helper used by window, visibility, and tray listeners.

🤖 Augment PR Summary

Summary: Adds Cmd+Up / Cmd+Down navigation to cycle between Home and enabled provider tabs in the panel.

Changes:

• Make the panel container programmatically focusable via tabIndex=-1 so it can reclaim focus on show.
• In usePanel, refocus the container on window focus / visibility restoration, and after tray-driven navigation/about events.
• Add Cmd+Arrow key handling to compute the next view (wraps at ends, skips Settings) and update activeView.
• Ignore Cmd+Arrow navigation when the event target is an editable control (inputs/contenteditable/role=textbox).
• Tighten usePanel typing by switching displayPlugins from unknown[] to DisplayPluginState[].
• Add focused regression tests for Cmd+Arrow navigation and focus recovery in use-panel and the full App.

Technical Notes: Key handling is attached at the window level and uses Meta-only (Cmd) with ArrowUp/ArrowDown; focus restoration is deferred via requestAnimationFrame.
