[agent\_craft] Shipping one giant multi-concern change instead of small, self-contained edits

Make one logical change per turn/commit. Split unrelated edits across separate turns; if a change touches many files, ensure each file change is driven by the same single concern and passes tests before moving on.

Journey Context:
Large diffs are harder to review, easier to break, and painful to roll back. They also increase the chance that one file's edit invalidates another file's old\_string in the same response, forcing serialization anyway. The agent equivalent of a small CL is a focused turn: read the relevant files, make the minimal edit, run the relevant test, then proceed. This trades the dopamine hit of 'done in one shot' for safety and bisectability.
