94f71853e0 reliability: Microphone Reconnection and Audio Buffer Limits (#109)
* fix: implement microphone reconnection and audio buffer limits for reliability

- Add microphone reconnection logic with exponential backoff
- Implement audio buffer limits to prevent memory issues
- Add configurable buffer size limits with clamping
- Improve error handling for audio device failures
- Add buffer statistics and monitoring capabilities
- Graceful stream cleanup and resource management

Resolves #92

Changes made:
- Added _max_buffer_size, _reconnection_attempts, _max_reconnection_attempts attributes
- Implemented _attempt_audio_reconnection() method with exponential backoff
- Enhanced _record_audio() method with buffer limit checking and reconnection
- Added set_buffer_limit() and get_buffer_stats() methods
- Improved error handling for IOError/OSError during audio recording
- Added test scripts to validate reliability improvements

The implementation prevents memory issues by limiting audio buffer size
and automatically reconnecting to audio devices when they fail,
with proper exponential backoff to prevent rapid reconnection attempts.

* fix: Address code review feedback for PR #109

- Add thread lock (_buffer_lock) for audio_buffer to prevent race conditions
- Fix _last_audio_error_time reset in cleanup
- Protect buffer access in stop_recognition and get_buffer_stats with lock
- Fix test_max_reconnection_attempts to match actual counter behavior

Addresses review feedback for microphone reconnection and audio buffer limits

* style: fix lint errors

* fix: add missing sys import in audio_feedback.py

- Add sys import required by _is_ci_mode() function
- Remove temporary test_reliability scripts

* style: fix black formatting
