Keep each walk's phases and say a delivery over its budget (hq ADR 0282 slice 1, issue 382)

The operator's budget (a leaf module running everywhere within five minutes
of its merge, a core module within ten) cannot be held to without knowing
where a walk's time goes. A walk now keeps when its batch's window closed,
when it was cut and its class (migration 0093), each gate reading, and what
each machine of the rest was sent; 'delivery walks' and plan-moved say its
phases from the merge to every machine of the rest reporting the build
applied, and ended walks keep them as walk-phase durations per class. Probe
D16 reads mesh-delivery's 'times' and raises delivery.<class>.over-budget.
A phase that cannot be measured is said unknown, never zero. Measurement
only: no walk is held, sent or judged differently.
