dsh--tools: A JSON Normalization Tool

The DSH plugin `dsh--tools` is designed specifically to address inconsistent key ordering and messy formatting in JSON processing. Built on Node.js, it supports recursive sorting of object keys, pretty-printing and minifying JSON, and is released under the MIT license. Users can install it via command and directly call functions such as `json_sort` within a session to format JSON and compare diffs. It is ready to use after installation; however, the source code should be reviewed before use to ensure security and compliance.
