feat: add killturn to general meta and update related tests

- Introduced a new meta property `killturn` to the GeneralMeta interface.
- Implemented a function `readMetaNumber` to handle the retrieval of numeric values from meta.
- Updated the `mapGeneralRow` function to ensure `killturn` is required and properly handled.
- Modified various tests to include the `killturn` property in the general's meta data.
- Adjusted related action files to utilize the new GeneralMeta type for better type safety.
- Ensured backward compatibility by updating existing test cases across multiple scenarios.
