Refactor: Reorganize fixture structure and update documentation

- Move fixture generation to separate repository (music_assistant_nicovideo_fixtures)
- Restructure fixtures: use fixture_data/ for generated data
- Update fixture loading to use new structure with fixture_type_mappings
- Remove embedded fixture generation scripts from tests
- Add comprehensive README for test directory
- Update VS Code tasks for easier fixture updates
- Delete obsolete GitHub workflow for fixture generation

+# Niconico Provider Tests
+
+Test suite for the Niconico music provider in Music Assistant.
+
+## Fixtures
+
+Test fixtures are JSON snapshots of Niconico API responses used for testing converters and business logic.
+
+### Updating Fixtures
+
+Fixtures are generated using a dedicated tool repository:
+
+**[music-assistant-nicovideo-fixtures](https://github.com/Shi-553/music-assistant-nicovideo-fixtures)**
+
+To update fixtures:
+
+1. Clone the fixtures repository (if not already cloned)
+2. Follow setup instructions in that repository
+3. Generate new fixtures with your test account: `python scripts/main.py`
+4. Copy generated fixtures `cp -r /path/to/music_assistant_nicovideo_fixtures/fixture_data tests/providers/nicovideo/`
+
+**Important:** Always use a dedicated test account, never your personal account!
+
+## Running Tests
+
+```bash
+# Run all nicovideo provider tests
+pytest tests/providers/nicovideo/
+
+# Run specific test file
+pytest tests/providers/nicovideo/test_converters.py
+
+# Run with coverage
+pytest --cov=music_assistant.providers.nicovideo tests/providers/nicovideo/
