Git Commit Message Writer

Write a commit message for this diff:

```diff
[PASTE_GIT_DIFF]
```

Follow Conventional Commits format:
`type(scope): short description`

Types: feat, fix, refactor, docs, test, chore, perf, style, ci
Scope: the area of code changed (component name, module, etc.)

Rules:
- Subject line under 72 characters
- Use imperative mood ("add" not "added")
- Body explains WHY, not WHAT (the diff shows what)
- Reference issue numbers if applicable
- If multiple logical changes, suggest splitting into separate commits

Output:
1. The recommended commit message (subject + body)
2. If the diff is too large: suggest how to split it into atomic commits, each with its own message
