dsh-minimal-UI-panels: DSH Right Sidebar Multi-Panel Integration Solution

After the architecture adjustment in DSH 0.1.5, the `dsh-minimal-UI-panels` plugin integrates the Artifacts, Memory, Terminal, and Notes panels into two tab types, managed through vertical stacking and draggable dividers, and supports split-screen display as well as code/memory search. Installed as a local linked dependency, it requires DSH 0.1.5 or later and cleanup of legacy plugin configuration, aiming to improve the operational efficiency of the DSH client.
