A claude tab drew no harness mark at all and every other agent CLI a
two-letter text pill (DS, CX, ...), so a claude tab read as "no harness"
next to its neighbours. Session tabs (header strip, side rail, sidebar,
phone chips) and the desktop home rail now draw the agent through PR
#532's run-mode-dot <id> slot, the id as data, the same mark the Run
menus and the tile and split headers use. The shell is not an agent and
keeps its SH pill; a CLI added through clis.json gets the slot's plain
dot instead of nothing.
The per-CLI tab pill colours and their light-skin ink overrides are gone
(the monochrome marks follow the tab's own text colour), and the logo
steps aside with the other adornments while a compact rail row renames.
