Schedule in-process JavaScript agent jobs with Croner

Croner is a zero-dependency JavaScript and TypeScript cron scheduler and cron-expression evaluator. Use it when an operator or coding agent is adding lightweight recurring work inside a custom agent service, such as periodic memory cleanup, report generation, polling, evaluation runs, or scheduled maintenance, and wants reviewable cron expressions with next-run inspection, timezone handling, pause/resume controls, async task support, and overrun protection. Invoke this instead of using a hosted scheduler or durable queue normally when the useful workflow is local in-process scheduling: install Croner, define bounded jobs in code, review the cron expressions and next-run behavior, wire error handling, and keep the scheduled task implementation inside the agent service. The scope boundary is embedded schedule evaluation and in-process recurring jobs for JavaScript runtimes, not a full job queue, distributed scheduler, monitoring platform, or generic npm library listing.
