Hanzo's app SDK, one package per directory under pkg/:
pkg/app— @hanzo/app, the shell and the first-party apps every Hanzo host draws (hanzo.ai, hanzo.team, Hanzo Desktop).
pnpm install, then pnpm typecheck, pnpm lint:design, pnpm test and
pnpm build run over every package. A package ships to npm when its
package.json names a version npm does not serve (.github/workflows/publish.yml).
