mesh-grants publishes memberships on change; the user list, assertions and grants stay in shadow (issue 1945)

Since release 6 nobody publishes memberships, so a module placed since cannot serve its seat
or reach a new state (the operator, 2026-10-25 22:31). The part publishes each membership on
the assignments stream only when it differs from the one last published, composes from the
manifest the wanted build names, and says a refused publish and tries again at the next event.
Pins mesh-sdk 881da7f, whose composer grants mesh-grants that publish.
