What it may solve
Four right-Sidebar panels for the dsh web client — an artifacts browser, long-term memory, a terminal and notes — paired two per tab with a draggable split, so two panes show all four at once. Ships the host half as well: nine memory_* tools, artifacts_list, the /memory command, the /api/artifacts/* and /api/terminal-notes/* routes. The terminal runs one bash command per line, with a 120-second deadline and a stop button. Requires dsh 0.1.5 or newer, which is where the right Sidebar replaced the old details column.
