dsh-dev-server: Lifecycle Primitives for the DSH Long-Running Development Server

`dsh-dev-server` is a workflow plugin in the DSH ecosystem designed to address lifecycle management of long-running server processes. It provides management primitives for precise control of server startup and shutdown, and simplifies environment configuration by blocking compound shell syntax. Its v0.1 version separates the registry, state, and host process supervisor, ensuring that execution permissions remain with the host environment (such as DSH and KerniQ). The plugin is built on Node.js >=20 and is released under the MIT License.
