dsh-cron-guard: Check if local cron jobs are stopped with one scan

A read-only inspection plugin maintained by feely0208 for scanning local launchd and cron jobs. It determines if tasks are stalled based on runs and exit codes, outputting the last success time, exit code, consecutive failure count, and log tail evidence. It classifies the results into four levels (Red/Yellow/Grey/Pass) and provides the exit code. It includes a dashboard, CLI, and configuration options.
