feat(memory): add session-based chat history and user metadata retrieval

- Add ChatSessionCache to manage chat history per session
- Add SEARCH_USER_METADATA cypher query for retrieving user entity metadata
- Add "str" mode support to StructResponse for raw text extraction
- Add content_str field to MemorySearchResult for pre-formatted content
- Fix sandbox URL by removing hardcoded port
- Add description field to entity search results
- Remove history from UserInput schema, use session_id instead

 - The questions SHOULD cover the main content of the text as much as possible.
-- The answers MUST be concise, accurate, and directly derived from the text content.
+- The questions MUST be in the same language as the given piece of text content.
-- The answers SHOULD be self-contained and understandable without additional context.
+- One question per line.
-- Both questions and answers MUST be in the same language as the given text content.
