Commitlint

Validate commit messages follow the Conventional Commits specification. Enables automatic changelog generation, semantic versioning, and clean git history.

What this skill does

1. Checks if @commitlint/cli and @commitlint/config-conventional are installed; installs them if missing.
2. Detects project-specific commitlint configuration or falls back to a sensible default config.
3. Validates commit messages for type, scope, subject, body, and footer format.
4. Reports errors with specific fixes and examples.
