Logbook lives in Harbor and keeps itself current

The board's Logbook view replaces the published page: statistics, the chart
of the executable, where the code stands (with the function tiers), the
trend, milestones and the ship's log, stored as JSON in the Harbor home.
A server thread follows main: each new commit becomes a log entry and the
statistics, chart and trend point are rebuilt with the open-seas progress
tools on a scratch copy. 'harbor logbook add|stats|map|milestone|refresh'.
