v2.7.0

This release introduces a significant enhancement to the lyrics detection pipeline by replacing generic web search with a specialized lyrics database integration, improving accuracy and search efficiency.

New Features:

• LyricsGenius Integration: Replaced the DuckDuckGo web search backend with the LyricsGenius library, providing direct access to the Genius database for more accurate and comprehensive lyrics retrieval.
  • Specialized Search Tool: Implemented lyricsgenius_web_search_tool as a dedicated search provider optimized for song and lyrics lookups.
  • Intelligent Query Cleaning: Added automatic removal of common LLM suffixes (e.g., "lyrics", "歌詞", "訳") that hurt search accuracy, ensuring cleaner and more effective queries.
  • Structured Results: Introduced new data models (SearchResult, QueryResults, WebSearchResponse) for better organization and type safety of search results.

Removals:

• DuckDuckGo Search Removed: Completely removed the DuckDuckGo web search option from the codebase. The web_search_tool configuration no longer supports duckduckgo as a provider, streamlining the search pipeline to focus exclusively on the superior LyricsGenius integration.

Prompt Engineering:

• Lyrics Detection (v5): Updated the lyrics prompt to reflect the new search capabilities and provide clearer instructions on query optimization for the LyricsGenius tool.
• Search Efficiency: The prompt now explicitly instructs the AI to leverage the specialized search tool's capabilities without appending redundant keywords like "lyrics" to queries.

Internal Tooling:

• Dependency Management: Added lyricsgenius to project dependencies in pyproject.toml.
• Code Quality: Maintained consistent Google-style docstrings and ruff formatting across all new modules.
