- Implemented KnowledgeHandler for managing knowledge groups and items, including listing, creating, updating, and deleting operations. - Added database migration scripts to create necessary tables for knowledge management, including knowledge_groups, knowledge_items, knowledge_parse_tasks, and knowledge_chunks_meta. - Introduced prompt_rule_knowledge_groups table to associate prompt rules with knowledge groups.
