laravel-extended-relationships

Use this skill when working with MrPunyapal Laravel Extended Relationships package. Activate when adding or fixing `belongsToManyKeys`, `hasManyKeys`, `hasManyArrayColumn`, or `belongsToArrayColumn` relationships, or when a Laravel model stores multiple related keys in columns or JSON array columns. Covers trait setup, relationship definitions, eager and lazy loading, inverse relationship patterns, and array-string matching. Do not use for standard Eloquent relationships that Laravel already supports directly.
