Report each tick's outcome and the updater's state to the master

The master saw a scheduler's last run time and nothing of what it did. Each
tick now records, per lane, its outcome, a line on what happened (what
fired, or the spread, contract or hold cap that stopped it) and why the
lane's accounts sat it out, counted by reason with a few names each. It
rides the scheduler status as lastTicks.

Each report also carries the auto-updater's state from the files it keeps
and from git: its last check, a failed update waiting to retry, how far the
checkout is behind origin, and tracked files edited by hand, which stop the
fast-forward pull.
