* Enhance audio processing and wake word detection - Set task priority in Application::Run to improve responsiveness. - Log detected wake words with their state in HandleWakeWordDetectedEvent. - Streamline audio feeding in AudioService to handle both wake word and audio processor events. - Implement input buffering in AfeAudioProcessor, AfeWakeWord, CustomWakeWord, and EspWakeWord to manage audio data more efficiently. - Clear input buffers on stop to prevent residual data issues. * Refactor audio processing to enhance thread safety and state management - Implement early return checks in Feed methods of AfeAudioProcessor, AfeWakeWord, CustomWakeWord, and EspWakeWord to prevent processing when not running. - Introduce std::atomic for running state in CustomWakeWord and EspWakeWord to ensure thread-safe access. - Consolidate input buffer management with mutex locks to avoid race conditions during Stop and Feed operations. * Refactor listening mode handling and wake word detection configuration - Replace direct mode setting logic with a new GetDefaultListeningMode method for improved clarity and maintainability. - Update HandleToggleChatEvent, HandleWakeWordDetectedEvent, and ContinueWakeWordInvoke to utilize the new method for determining listening mode. - Introduce Kconfig option WAKE_WORD_DETECTION_IN_LISTENING to enable or disable wake word detection during listening mode, enhancing configurability.
