Provides a reusable caching macro that generates cached and uncached versions of API data fetching methods, along with a self-cleaning cache mechanism. The macro encapsulates cache logic, automatic parameter normalization (like downcasing), and periodic cleanup via a cron job. This component is isolated (depends only on memory_cache and tasker shards) and demonstrates advanced metaprogramming skills for creating generic, reusable caching solutions.

Defines a DelimitedString structure for storing and manipulating lists of strings as a single delimited string (newline-separated). Includes safety checks to prevent newline characters in elements, ensuring data integrity when stored in databases. This utility is completely self-contained with zero dependencies, making it trivially extractable for any application needing to store comma/list data in a single database column or configuration setting.
