vecnode/dsh-rightbar

Right bar: vncode' own right Sidebar for the DeepSeek Harness web GUI - the tab strip, the docking panel, the expand control, the tab-type registry (sidebarRightTabs/sidebarRight), the keyed tab seats and the Start/guide page. Vendored from the shipped @deepseek-ai/dsh-client-ui-sidebar-right bundle so the pack owns the code, with the patch list in scripts/sync-vendored.ps1 applied on top (today: the dock's two-pane cap lifted to the kit's own four, all five drop zones offered, and the dock RENDERED by the kit's recursive DockSurface - the flat DockLayout throws on anything but two panes side by side, so a stacked pane used to retire the bar until a reload); the bundle layer disables the core row. Alpha.
