Inefficient file deletion

[NikitaKurpas]

Issue

Hey!
First of all, amazing tool—I love using it! Thank you!

During a major refactor, I noticed some inefficient behavior in the model. When moving a large chunk of logic from a file (e.g., ai.py) to other files, it then attempted to delete ai.py. However, instead of simply generating an rm command (or something similar) with the filename, it output an entire search-replace block, where the SEARCH section contained the file’s full contents, and the REPLACE section was empty.

Since the file itself was large, this approach seemed unnecessarily wasteful just to delete it.
