Summary
Add thread-safe locking for wake word reload logic
Problem
Wake word reload logic accessed self.state.wake_words_changed flag without synchronization, creating a potential race condition when wake words are dynamically switched via Home Assistant.
Changes
Added self._wake_words_lock = threading.Lock() in __init__
Wrapped wake word reload block with with self._wake_words_lock: context manager
Ensures atomic read-modify-write of wake_words_changed flag
Impact
Risk: Very low - purely defensive improvement
Benefit: Eliminates race condition in wake word switching
Performance: Negligible overhead (lock only held during reload check)
