🤖 fix: add Ctrl+I focus keybind to new chat page (#1102)

The new chat page (workspace creation flow) displays "⌘I to focus" but
the keybind wasn't actually registered there.

**Problem:** The `FOCUS_CHAT` keybind handler was only in
`useAIViewKeybinds` (used by `AIView.tsx` for existing workspaces), but
not in `App.tsx` where the creation variant of ChatInput is rendered.

**Fix:** Added the `FOCUS_CHAT` keybind to App.tsx's global keydown
handler, which focuses the creation chat input when on the new chat
page.
