   *    - Created by AgentVibes installer
   *
   * 2. .claude/hooks/play-tts.sh
   *    - Core TTS router (ElevenLabs or Piper)
   *    - Provider-agnostic interface
   *    - Required by bmad-speak.sh
   *
   * Why Both Required:
   * ==================
   * - bmad-speak.sh alone: No TTS backend
   * - play-tts.sh alone: No BMAD agent voice mapping
   * - Both together: Full party mode TTS integration
   *
   * Detection Strategy:
   * ===================
   * We use simple file existence (not version checks) because:
   * - Fast and reliable
   * - Works across all AgentVibes versions
   * - User will discover version issues when TTS runs (fail-fast)
   *
   * PATTERN: Adding New Detection Criteria
   * =======================================
   * If future AgentVibes features require additional files:
   * 1. Add new pathExists check to this function
   * 2. Update documentation in promptAgentVibes()
   * 3. Consider: should missing file prevent detection or just log warning?
