This commit enhances the .gitignore file by adding entries for runtime caches, TTS/audio outputs, and Python-related files. The changes ensure that unnecessary files are excluded from version control, improving repository cleanliness and reducing clutter.
Changes:
- Added entries for edge_tts_voices_cache.json, *.wav, and *.mp3 files.
- Included Python cache directories and virtual environment folders.
- Retained existing entries for build artifacts and IDE/editor files.
