The baseline is the only notice that a watch started against an already
conflicted PR, and it was missing from the mode automation uses. It goes to
stderr as a JSON record, leaving stdout a single result record.
Merge-input movement arms the conflict rule and no longer clears the run of
non-mergeable observations, so an arming poll's own false cannot be half the
evidence and a base branch moving under every poll cannot starve a real
conflict. The run must now span conflictWindow, measured on the tick that
fired each poll.
A mergeable=false baseline meant a conflict could never be reported, since
Gitea sends false while it recomputes after a push. Arm on a head or base SHA
change as well as on a mergeable poll, break the conflict run on unknown and
failed polls, and print the baseline with the conditions it suppresses.
Track mergeability across the whole run and decode it as a tri-state, so a PR already conflicted when watching starts is polled on instead of reported.
