Cron Expression Parser
Parse a cron expression into a plain-English schedule. Nothing is ever sent anywhere.
Supports standard 5-field cron (minute hour day-of-month month day-of-week) plus the common @daily/@hourly/etc. shortcuts. It does not support 6-field "seconds" cron (Quartz/Spring) — that's a different, incompatible syntax, not a variant of this one.
Parsed locally. Never sent anywhere.
