Let a recorded module's move that restarts nothing roll out with its walk (issue 785)

Under a module's own record (its manifest's, or its irreplaceable data's), every
move waited for a person's push, even one that only changed a tools bundle: the
database server stayed behind on ace on 2026-10-15 although its walk said it
recreated none of its containers. ADR 0377 lets such a move roll out.

A move is judged per machine against the build that machine was last sent: it
goes when no container, mounted file, data path, data declaration, provider or
(for a module with data) long-running process changes. A person's record, the
bus and any move that cannot be judged still wait. The walk keeps per machine
which way each recorded module went and why, says it in its note and log, and
status names a machine behind with `push <node>` only for a move that waits.
