"""Desktop tool consolidation + diet (#95681, maintainer-directed).

preview = open/close/read as one action tool (576 -> ~235); project =
create/switch/list as one (244 -> ~155). Old names are GONE from the
toolsets (desktop-only tools; no long-transcript compat needed). The
preview read action still routes through the agent-level GUI callback.
