v1.0.2 moved the verdict off watch-build's exit code, but left the step
silent for the whole build: COPR emits nothing between state transitions,
and the poller only spoke at the end.
That silence is itself the failure. Two monsoon releases died after ~24-27
minutes of no output at all — run 48 at 08:35:50 with COPR having succeeded
at 08:30:30, and run 50 at 09:35:50, 66 seconds *before* COPR reported
success at 09:36:56. A build finishing either side of the kill rules out a
build-duration timeout and points at an inactivity timeout on the runner.
Print a line on every poll with elapsed time and current state. It keeps the
step producing output for as long as the build runs, and makes the log show
progress instead of a 25-minute gap. Heartbeats go to stderr because stdout
carries wait_for_terminal_state's return value.
Test covers a build that stays running across several polls before
succeeding, asserting the heartbeat appears.
