Task 1: Replace hardcoded VoiceLister bypass in get_voices() - Use PluginManager → Engine → VoiceLister instead of direct imports - No more hardcoded imports of plugins.kokoro.engine / plugins.supertonic.engine Task 2: Remove SuperTonic Plugin dependency on legacy backend - Create self-contained plugins/supertonic/pipeline.py - Plugin no longer imports from abogen.tts_backends Production code now has zero imports from: - abogen.tts_backend - abogen.tts_backend_registry - abogen.tts_backends
