Description

[^\]] = mapped_column\(

@dosu list all the files need to update and tell me how to do it.

Contributor guide

Research direction
Explore the Dify backend code to locate all SQLAlchemy models using `mapped column` without `Mapped` annotations. Identify the files that need changes and understand how column types are currently defined. This will help you list the required files and plan the migration to explicit `Mapped` annotations.
