Finding 6: every module requires the mesh modules it builds with

The SDK, the assigner, the builder's buildrun, the indexer, the
pipeline, the watchman, mesh-enrolment and mesh-grants (and through the
SDK the checker's checkermsg and mesh-tools' node-tools) imported
packages of modules their go.mod did not require at the zero version;
the placement's go.work over the whole repository hid it, and a build
of the module alone with -mod=readonly refused it. Each now requires
them (beside a relative replace where the module keeps its siblings so),
and the indexer's and watchman's duplicated lines go.

Builds: design 47 G §427 (the group's check builds every importer); delivery review round 1, finding 6
