Fix return value check for methods with returning option

[xterao]

Describe the bug
Currently, when using SQL templates for Insert, Update, and Delete (including Batch operations), the return type check enforces that the return value must always be of type int or int[].

  @Insert(sqlFile = true)
  Result<Dept> insertBySqlFile(Dept entity);

Expected behavior
In practice, when the input parameter is an immutable Entity class, the expected return type should be Result or BatchResult.
This issue will revise the check logic to correctly handle this case.
