Keep the packages this node's compositions declare in the engine's own key, and answer them on the node seat (ADR 0565 clauses 6 and 15, issue 1953)

Browse Source 
pacman still reads the controller's mirror because no engine wrote its key: the engine
now keeps each handed composition's package resources and, after a pass that handed
something new, writes mesh-host_packages.<node> only when the value differs, owed after
the growing bound when refused. The manifest declares the state so the grants part
creates it. The verb packages answers the key beside the mirror's key for the node and
their difference, and with write writes the key again from what was composed. H8's
integration test proves the write under the grant the grants part composes.

Needs mesh-sdk feat/node-packages (0ef7c0c) for DeclaredPackagesOf and the engine's read of the
mirror (go.mod pin left for the lead: the SDK commit is not pushed).
