dsh-nushell-only: Nushell-Exclusive Executor for DeepSeek Harness

The DeepSeek Harness plugin `dsh-nushell-only` takes over the shell execution layer to enforce that the model uses only Nushell. It introduces modifications across four levels: disabling the built-in sandbox and replacing it with a custom executor, preventing the model from switching to other shells, providing prompt-based instruction in the Nushell dialect, and intercepting and correcting common Bash/PowerShell syntax errors. It is compatible with DSH 0.2.0-rc.2 and is suitable for developers who want a unified shell ecosystem.

dsh-nushell: DeepSeek Harness Profile Bundle for Nushell

`dsh-nushell` is a Profile Bundle maintained by daief, intended to replace Bash tools with Nushell syntax in DeepSeek Harness (DSH). By converting Bash invocations into `nu --no-config-file -c` commands, it reuses DSH's sandboxing and timeout mechanisms. Installation requires DSH 0.1.0-rc.7 and a Node.js 22.19.0+ environment. The plugin is stateless, does not depend on configuration files, requires `workdir` to be explicitly specified, and provides developers with a lightweight Nushell-based data processing solution.
