W13.5: the node agent asks mesh-recovery for a restore point before a form change and restores it at a revert

Browse Source 
Before a move across a kept data's form change the node agent asks snapshot-kept and waits for the ended of its own act; at a revert it stops the newer build (Env.Stop), asks kept-points, asks restore-kept with the snapshot of the point of the form and fingerprint it reverts from, waits for restored, applies the reverted build, and calls the point's catch-up as the module's tool through the tool runner. The wait is in the have (ask-at, act), bounded by a bounds key of the state bounds (recovery-wait-minutes, 90), and each ending is read as the table of 560 says. The manifest consumes mesh-recovery's ended and restored and invokes its three verbs.

Builds: design 47 G §296, §297, §554, §555, §560, §630, §631, §632, §633, A-77, A-92, A-98, A-108
