Pull Request Overview

This PR fixes iOS simulator recording issues by implementing a retry mechanism for audio tap installation, addressing format availability timing problems that commonly occur on iOS simulators.

• Refactored the audio tap installation to use a retry-based approach with proper error handling
• Added new instance variables to track retry state and prevent concurrent tap installations
• Moved audio engine startup to occur before tap installation to ensure proper format availability
