Release 2.2.12

This release adds thumbnail URL validation to prevent display of broken images, fixes citation generation issues, and improves reliability of VFB data presentation.

Changes:

• Added async thumbnail URL validation using axios.head to check image existence before inclusion
• Modified summarizeTermInfo function to validate thumbnail URLs with 2-second timeout
• Updated system prompt to restrict citations to VFB data only - prevents LLM from generating random DOIs
• Enhanced publication extraction to include FBrf IDs from Synonyms field in addition to Publications field
• Prevents LLM from hallucinating invalid URLs like malformed template IDs (e.g., /VFB_001011rk/)
• Added error handling and logging for failed thumbnail validations
• Improved user experience by filtering out broken image links and irrelevant citations
