Subject: [PATCH] fix(web): a command you stop stays in the timeline

Stopping a turn mid-command marks the command interrupted, which the
work log maps to "stopped". The timeline treated stopped calls as
neutral (neither success nor failure) and filtered them out like empty
rows, so the command vanished once the run settled. Stopped is an
outcome, so keep it visible, as mobile already does.
