What it may solve
Hierarchical workspace tree for the DSH sidebar: every slash in a workspace title becomes a virtual folder (arbitrarily deep), the add-workspace directory flow gains a parent-group popup, renames re-derive the tree instantly, sessions nest on the same rule with separate visual styling, and every row carries right-click actions plus per-row appearance customization (color, text-only glow, font weight, primitives-family icon).
