What's new

/cadenza:commit — atomic commits with generated messages

Analyses your changed files, groups them into logical atomic commits, generates conventional commit messages, and asks whether to push at the end. Accepts inline exclusion hints:

```
/cadenza:commit
/cadenza:commit without .gitignore
/cadenza:commit only src/
```

commands/ → skills/ migration

All skills have been moved to the current skills/<name>/SKILL.md format, replacing the legacy commands/*.md layout.
