fix todo

• veadk/database/database_adapter.py
  • VectorDatabaseAdapter, The query function has been confirmed to not require validation and will return [] (because a not exists judgment mechanism is designed at a lower level).
  • vector: the _validate_index has been added, and the document link has also been added.
  • viking's _validate is the same as above
  • viking-mem's _validate is the same as above
  • viking's get_or_create_collection function. After creating the collection, you need to wait for a while. The subsequent while loop is used to check if the creation was successful.
  • the query of viking directly returns []
  • viking-mem, add function parameter user_id
• veadk/database/viking/viking_memory_db.py, code source comments have been added
• veadk/knowledgebase/knowledgebase.py added type checking for non-viking cases
