feat: expose CAD dimensions (mm) in chat agent tools

Browse Source 
- search_products now returns dim_x_mm, dim_y_mm, dim_z_mm from
  cad_files.mesh_attributes->'dimensions_mm'
- query_database tool description updated with cad_files schema
  including mesh_attributes->'dimensions_mm' path
- AI can now answer "what's the biggest product?" using real dimensions
