dsh-artifact-preview: Integrating Agent Artifact Preview into the DSH Chat Interface Client Plugin

# Introduction When using DSH to run agents, models frequently generate multiple files in a single turn of dialogue through tools like write/edit: Markdown reports, scripts, CSV data, and HTML pages.
