* feat: add return_fields parameter to search methods (#955) Add optional return_fields parameter to search_by_embedding, search_by_keywords_like, search_by_keywords_tfidf, and search_by_fulltext methods across all graph DB backends (neo4j, neo4j_community, polardb). When return_fields is specified (e.g., ['memory', 'status', 'tags']), the requested fields are included in each result dict alongside 'id' and 'score', eliminating the need for N+1 get_node() calls. Default is None, preserving full backward compatibility. Changes: - base.py: Updated docstring for search_by_embedding - neo4j.py: Added return_fields to search_by_embedding, modified Cypher RETURN clause and record construction - neo4j_community.py: Added return_fields to search_by_embedding, added _fetch_return_fields helper for direct vec_db path - polardb.py: Added return_fields to all 4 search methods, added _extract_fields_from_properties helper for JSON property extraction Closes #955 fix: add field name validation to prevent query injection in return_fields - Add _validate_return_fields() to BaseGraphDB base class with regex validation - Apply validation in neo4j.py, neo4j_community.py, polardb.py before field name concatenation - Add return_fields parameter to base class abstract method signature - Revert unrelated .get(node_id) change back to .get(node_id, None) - Add TestFieldNameValidation and TestNeo4jCommunitySearchReturnFields test classes (7 new tests) fix: resolve ruff lint and format issues for CI compliance * feat: add optimize user_name && key words && log (#1111) * feat:optimize user_name && key_words * feat:optimize user_name && key_words * hotfix: An error occurred when adding the edge of the graph.

Using except Exception ensures system-level exceptions propagate.
