Hey @omeraplak 👋

I'd love to take this on! LanceDB's multimodal capabilities align perfectly with modern AI agent workflows, and I see VoltAgent already has great database integrations like Pinecone and LibSQL that I can use as reference.

My approach:

1. Study existing patterns - Review the Pinecone and LibSQL integrations to understand VoltAgent's database adapter architecture
2. Design the integration - Create a LanceDB adapter following VoltAgent's conventions for vector storage, retrieval, and memory management
3. Implement core features:
   • Vector storage with embeddings
   • Similarity search with configurable distance metrics
   • Metadata filtering and hybrid search
   • Multi-modal data support (text, images, etc.)
4. Testing & docs - Comprehensive tests and usage examples
