-- Herdr second-runtime path (Phase 1a).
--
-- Missions can now execute either through the shared ZeroClaw daemon
-- (default, headless, browser-driven) OR through a Herdr session on
-- a specific fleet node (attended, operator-visible, uses that node's
-- local CLIs). Frontend picks in the wizard; mission_orchestrator +
-- phase executors dispatch on runtime_kind.
--
-- topology_runs grows a nullable (workspace, tab, pane) triple so a
-- run resumed after a server restart can reattach to the same Herdr
-- pane instead of spawning a duplicate.
