feat(ui): Interactive chip for tasks with an open ConPTY session

A task driven by hand in Mission Control is Idle with an Active worktree, so its
lifecycle chip read "Parked" — indistinguishable from a task genuinely set aside.
The shell now mirrors Mission Control's open panes onto the rows, which show an
accent "Interactive" chip instead; tapping it surfaces Mission Control and
focuses that pane (the open command already dedupes by task id).
