Fix: Audio Device Reconnection Logic for Long-Running Sessions

related issue: #1626

Problem

Audio recording was stopping after extended periods (48h+) on macOS due to device disconnections without proper reconnection handling. The system would fail permanently when a device disconnected instead of attempting to recover.

Solution

Implemented a robust device reconnection system with configurable retry logic:

Key Changes

• Added device-specific reconnection tracking with reconnect_attempts
• Implemented maximum reconnection attempts (10) with 5-second delay between attempts
• Added proper device state management through is_disconnected flag
• Improved logging for reconnection attempts and success/failure states

Technical Details

const MAX_RECONNECT_ATTEMPTS: u32 = 10;
const RECONNECT_DELAY: Duration = Duration::from_secs(5);

• Tracks reconnection attempts per device
• Resets attempt counter on successful reconnection
• Maintains device state through atomic boolean flag
• Provides detailed logging of reconnection progress

Testing

• Verified long-running stability (>72h) on macOS
• Tested recovery from device disconnections
• Confirmed proper reset of reconnection attempts after successful recovery

Notes

• No changes to core audio processing logic
• Maintains existing whisper integration
