- Moved TTS nodes into a dedicated 'nodes' directory for better organization.
- Introduced a base class `NodeTTSBase` to handle common functionality for TTS nodes.
- Added new TTS nodes: `TTS_KokoroNode`, `TTS_ChatterboxNode`, `TTS_StyleTTS2Node`, `TTS_KittenTTSNode`, `TTS_F5TTSNode`, and `TTS_GlobalPresetNode`.
- Updated the main module to include mappings for new nodes and their display names.
- Removed the old `tts_webui_openai_tts.py` file and integrated its functionality into the new structure.
- Created utility functions for audio processing and file handling in the `utils` module.
- Added unit tests for the `TTS_ChatterboxNode` to ensure functionality and reliability.
- Deprecated the `_shared.py` module in favor of explicit per-node payloads and the new base class.
