🔀 refactor(types.py): add langchain_types_dict as a separate variable to improve code readability and maintainability
The import statement in `endpoints.py` has been updated to import `langchain_types_dict` instead of `build_langchain_types_dict` for consistency with the variable name. This change improves code readability and maintainability.
In `types.py`, a new variable `langchain_types_dict` has been added as a separate variable to store the result of `build_langchain_types_dict()`. This change improves code readability and makes it easier to understand the purpose of the variable.
