The delivery repository's contracts and SDK live under modules/ as
mesh-delivery-contracts and mesh-delivery-sdk, their Go module paths
renamed to match the folders (the TypeScript names already did), and
every importer in mesh-delivery, mesh-catalog, mesh-host, mesh-tools
and mesh-sdk follows in the same group: a design as it should be, one
path per module, checked by the group's check building every importer.

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lane key, the unpublished modules, the toolchain sources, the ends watched, the sayer and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).

BL8 (8255eb28) replaced buildrun's ToolchainGate, ToolchainSet.Put and ToolchainsBucket by PlacedNodes and ToolchainSet.Set for the builder
(§546, §604); no design line removes the checker's and the indexer's toolchain reads, so the three come back beside them, and
FollowAssignments feeds either.

The builder agrees a language's toolchain from the three build seats'
toolchain-reported, kept in its state toolchains-heard (read back at its start),
forgets a node's on the node-engine seat's running with no fingerprint (stopped)
and never on a placement, says toolchain-agreed with its digests list only when
the agreed version changes; builder_toolchains and builder_toolchains_drop;
the manifest's reads of the build modules' toolchains are gone. The gate over
the assignments is now PlacedNodes, which only counts nodes.

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).
