[agent\_craft] How to write commit messages that don't lose change context

Separate the subject from the body. Use imperative mood in the subject \(<=50 chars\), capitalizing the first letter and omitting trailing periods. Wrap the body at 72 chars, explaining the 'why' and tradeoffs, not the 'what'.

Journey Context:
Agents often write commit messages that mechanically describe the code \(e.g., 'updated index.js'\) or provide irrelevant detail. The imperative mood \('Fix bug' not 'Fixed bug' or 'Fixes bug'\) matches Git's own generated messages \(e.g., 'Merge branch'\). Explaining the 'why' in the body prevents future developers—or the agent itself in a later session—from reverting a fix because they don't understand the original constraint.
