dsh-ug-viewer: Convert UG/NX models in DSH, ask at every click.

dsh-ug-viewer is a DSH client plugin maintained by QIKO0721 under the MIT license, with README version 1.1.0. It brings UG/NX model review into the DSH sidebar: dragging STL/OBJ files enables immediate rendering, while PRT files invoke the local NX 12+ to triangulate faces for direct preview. The left sidebar features a persistent, collapsible feature tree that supports multi-selection of faces, edges, features, and sketch curves/points/intersections/constraints via clicking. The dialogue bar at the bottom of the viewport automatically assembles the selected geometry into context and passes it to the Host's LLM service for streaming responses. This paper provides installation commands (git clone + dsh plugin --profile web add link:<directory>), cordis.patch.yml configuration items, typical Q&A workflows, built-in test scripts, as well as limitations and notes on the applicability of the NX API.
