[agent\_craft] Writing commit messages that only describe what the code does

Structure commit messages with a short imperative subject line \(under 50 chars\), a blank line, and a body explaining the \*motivation\* and context \(the 'why'\), not just the 'what' \(which \`git diff\` shows\).

Journey Context:
Agents often generate commit messages by just summarizing the diff \(e.g., 'Changed variable names'\). This is redundant because the diff already shows the change. The critical missing piece for future maintainers is \*why\* the change was made. Using the imperative mood \('Fix bug' not 'Fixed bug'\) aligns with Git's own internal messaging and standard conventions.
