/**
 * Tests for CommandInputBar.tsx
 *
 * Comprehensive test coverage for the mobile command input bar component.
 * Tests include:
 * - Pure helper functions (isSpeechRecognitionSupported, getSpeechRecognition, triggerHapticFeedback)
 * - Custom hook useIsMobilePhone
 * - Component rendering in various states
 * - Controlled vs uncontrolled mode
 * - Input mode switching (AI/Terminal)
 * - Form submission handling
 * - Keyboard handling (Enter behavior)
 * - Visual Viewport API keyboard detection
 * - Slash command autocomplete triggering
 * - Voice input functionality
 * - Long-press quick actions menu
 * - Mobile expanded mode
 * - Recent command chips
 * - Swipe up gesture handling
