[WIP] Client Interface Implementation

[Copilot]

Thanks for assigning this issue to me. I'm starting to work on it and will keep this PR's description up to date as I form a plan and make progress.

Original issue description:

Primary Task: Complete Client Interface Implementation (Task 5.1)

Context

The SpotifyScraper library modernization is 60% complete. You're tasked with completing the client interface (client.py), which serves as the main entry point for users. This component integrates all the extractors, browsers, and media handlers into a unified API.

Specifications

• File location: src/spotify_scraper/client.py
• Dependencies: All extractors (track, album, artist, playlist), browser components, and media handlers are implemented
• Key requirements:
  • Implement all missing methods in the SpotifyClient class
  • Methods should support both URL and ID-based access
  • Add support for the extractors previously implemented (album, artist, playlist)
  • Maintain consistent error handling

Implementation Details

1. Implement these methods based on existing extractors:

   def get_album(self, url_or_id: str) -> Dict[str, Any]:
       # Extract album information using AlbumExtractor
   
   def get_artist(self, url_or_id: str) -> Dict[str, Any]:
       # Extract artist information using ArtistExtractor
   
   def get_playlist(self, url_or_id: str) -> Dict[str, Any]:
       # Extract playlist information using PlaylistExtractor

2. Add utility methods for ID extraction and normalization:

   def _normalize_id(self, url_or_id: str, expected_type: Optional[str] = None) -> str:
       # Convert URL to ID or validate existing ID

Secondary Task: Implement Package Initialization (Task 5.2)

Once the client interface is complete, implement the package initialization in src/spotify_scraper/__init__.py. This file should expose the public API and provide backward compatibility with version 1.x.

Testing Tasks (Tasks 6.1, 6.2)

After completing the client implementation, create test fixtures in tests/fixtures/ and implement unit tests for all components, focusing on:

• URL utilities
• Extractors
• Client interface

Final Task: Update Packaging Configuration (Task 6.4)

Update setup.py, pyproject.toml, and setup.cfg to prepare for PyPI release.

Success Criteria

• All methods are implemented with proper docstrings
• Methods handle both URL and ID inputs correctly
• Error handling is consistent
• Code follows type hints and best practices

Fixes #30.
