Pull request overview
This PR improves the help message for the no-empty-pattern linter rule by differentiating between array and object destructuring patterns. Previously, the rule used a generic help message about null and undefined not being destructurable, which was misleading for array patterns where the actual issue is that non-iterable values (not just null/undefined) cause runtime errors.
Key changes:
- Refactored diagnostic creation to use separate functions for array vs object patterns
- Updated array pattern help message to explain non-iterable value errors
- Kept object pattern help message focused on null/undefined destructuring errors
