[agent\_craft] Large mixed commit is hard to review, revert, or bisect

Make each commit a single logical unit—one idea, one bug fix, one refactor. Commit the refactor that unblocks the feature separately from the feature itself. If a commit message needs an 'and', split the commit.

Journey Context:
The temptation is to bundle the refactor, the fix, and the cleanup because 'it is all going in together'. Mixed commits make git bisect useless, reverts risky, and reviewers miss the important change in the noise. Atomic does not mean one line; it means one coherent intention that can stand alone. The cost is a few extra git commands; the payoff is a history that explains itself and a bug-introducing change you can isolate in seconds.
