Code Review
This pull request introduces a cleanup-goheader command to remove legacy data from the store. The implementation is straightforward, but I've found a critical issue that will prevent compilation due to an undefined variable. I've also pointed out a potential memory issue when deleting a large number of keys and suggested an improvement for robustness. Once these are addressed, the command should work as intended.

The variable evmDbName is not defined in this file or package, which will cause a compilation error. It should be defined, likely as a constant, representing the name of the EVM database.

This function loads all delete operations for a given prefix into a single batch. If there are a very large number of keys to delete, this could lead to high memory consumption. Consider processing the deletions in smaller batches (e.g., committing every 1000 keys) to limit memory usage and make the operation more robust against large datasets.
