capacities (25.5a): @max(n) on a list field, and a full table is a failure

Browse source 
'@max(64) boxes: []Box' on a property's or a state's field is a promise: the grow path of a push to
that field (only the grow path, so nothing is paid until it doubles) checks it, and growing past n is
reported by the fence - 'PoolState.boxes grew past its @max(16) (it holds 16)' - counted under
count, said under warn, and under fail (a headless or dev build's default) the run ends with exit 87.
Mem.over("what") is the same for a package's own table: ludic.base's StrTable past its most
(sb_intern) and ludic.ui's memo past three quarters of MM_CAP no longer quietly copy per call. The
census counts overflows.
