A module whose only artifact is a Go package (mesh-wireguard's go-overlay) never had a
done build: PlanOf refused every package of language go. The Go build module already packs
and publishes a Go package; the builder now asks it.
Builds: design 47 G §370; design 51 *Publishing*

The builder finds a build module as the indexer's seed does: the build seat whose acting rule
`build` has an `on` matching the artifact's language or kind:image, and that seat's holder, read
from the seat list's definitions and the claims of the catalog half's manifests. Task.Module, every
lane key, the unpublished modules, the toolchain sources, the ends watched, the sayer and
builder_stuck (through `<seat>.steps`) derive from it; the floor's sources are the holders of the
seats git and mesh-catalog. buildrun.GoBuildModule, NodeBuildModule, LanguageOf,
buildstep.BuildModuleOf use, build.ImageBuildModule and StuckBuildModules are gone from the builder
(the checker keeps its own names in two small files until its part reads them from the list).
Builds: design 47 G §7, §428, §704, §204, A-82

versions.NumberedBody and NumberedEvent are mesh-sdk's delivery.VersionNumbered and VersionNumberedEvent now (J3), the
contract a build module consumes for BG2's late publish; the body's JSON is unchanged. The lane reads a step's
out-of-step files through delivery.BuildAnswer.OutOfStep, a failed step's result too (as before, A2k's d15d66fc: read
before the step's state; its three rows hold it), in place of a local decode by name. The integration test hears
version.numbered on delivery.VersionNumberedSubject and reads it with DecodeVersionNumbered, as a build module does.

buildrun leaves mesh-sdk for the builder's own Go module (ADR 0593 §1); the
checker, assigner, indexer and watchman require it by a replace to the sibling
directory. Issue 1930's bound was already on mesh-sdk's main and moves with it.
The builder copies the imports a build module answers to the done key and the
log's end entry, where the indexer keeps them (§2; D7).
