dsh-neon: Neon Element Data Lookup Plugin

`dsh-neon` is a DSH plugin implemented entirely in Node.js, designed to provide chemical data for neon through local interfaces without relying on external network requests. Maintained by uckkk, it offers two core features: `element_info`, which retrieves complete information about neon (such as its atomic number and electron configuration), and `element_field`, which allows extracting specific data by field name. Installation requires the `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` dependencies and can be performed via the command line. This tool provides developers with a convenient way to access standardized data.
