LINGTIAN303/dsh-layout

Layout plugin for DSH: customize the structure, order, width and visibility of the left sidebar, right sidebar, conversation area and settings page. Drag-sort and resize the three columns, per-layer teardown of sidebar/conversation/right/settings, grid slot arrangement, draw-a-frame region relocation, entry consolidation into More menus, conditional linkage rules, multiple named layout schemes, and a fullscreen layout whiteboard with a four-layer structure tree. Config persists host-side; dangerous configs have multi-layer recovery entries.
