The tool runtime's manifest names the SDK as a git dependency at a pinned commit;
its lock file names a sibling directory that exists on one workstation. It builds
only because the recipe runs npm install, which tolerates a lock disagreeing with
its manifest and re-resolves from the manifest — the one command that hides this.
It matters because a lock exists to make a build reproducible and this one
describes one machine, and because it is the first thing a fresh mesh builds: the
toolchain carries the SDK and everything with code of its own compiles inside it,
so a dependency resolved differently on the build machine than on a workstation
is a difference in every module the mesh will ever build.
And it is about to be copied. Each language's toolchain will carry that
language's SDK the same way, so the shape is worth settling before there are four
of them.
