commit contains submodule/gitlink hunk

Error message

commit contains submodule/gitlink hunk

What it means

generate_evaluation_example_from_ordered_commit refuses commits whose diff contains a submodule/gitlink hunk; such entries cannot be replayed as text edits, so example generation from that commit is unsupported.

Solutions

1. Pick a commit without submodule changes
2. Filter out gitlink hunks from the diff before generation if supported
