dsh-business-days: Calculating Business Days

The dsh-business-days plugin for DSH is designed to provide agents with native business-day calculation capabilities, supporting the exclusion of weekends and holidays based on dates to help build smarter business workflows. Maintained by istone, it is implemented in pure Node.js, does not rely on external network interfaces, and supports offline use. Installation is simple, requiring only a single command to enable. Users can directly invoke its tools within a conversation. Since the plugin runs with process-level privileges, it is recommended to review the source code and license before use.
