**Summary:** Added CMD+Enter keyboard shortcut to the CreateAttemptDialog by:
1. Importing `useKeySubmitTask` and `Scope` from `@/keyboard`
2. Adding the `useKeySubmitTask` hook that calls `handleCreate` when:
- The dialog is visible (`modal.visible`)
- Creation is allowed (`canCreate` - profile and branch selected, not loading, not already creating)
This follows the same pattern used in other dialogs like `RestoreLogsDialog.tsx`.
