fix(commands): declare the zod runtime dependency of the generated faces

Exporting `./typert` and `./remote` ships two generated modules that
`import { z } from 'zod'`, and the package declared no runtime dependency at
all. Under pnpm's isolated layout nothing resolves zod for it — there is no
root `node_modules/zod` to walk up to — so loading the plugin tree failed with
ERR_MODULE_NOT_FOUND the moment a composition mounted the commands typert
face. The two other packages exporting `./typert` both declare it; this
matches them.
