scott a196294d4a Fix Wyoming protocol: remove SynthesizeStopped from Synthesize path ...

The plain Synthesize event (HA's standard TTS path) should NOT be
followed by SynthesizeStopped. That event belongs only to the streaming
protocol (SynthesizeStart/Chunk/Stop). Sending it after Synthesize
confuses HA's Wyoming client, causing it to hang indefinitely.

Also:
- Guard Synthesize path against duplicate events during streaming
- Send audio as one AudioChunk per sentence (matches working reference)
- Remove numpy import (no longer needed)
