Caution Review failedThe pull request is closed. WalkthroughDefault template options toggled to true in template.json; README template conditions inverted accordingly. Added commented EF Core query-splitting hints. ProductEmbeddingService now builds structured embedding inputs, fetches embeddings for queries, falls back to text search if unavailable, and applies pgvector similarity for PostgreSQL; SQL Server path retained via directives. Chatbot tool adds optional price filters. Changes
