chore(hygiene): restore the cordis peers and teach knip the split faces

`@deepseek-ai/cordis` returns to the peer and dev dependencies of
`dsh-client-ui-model` and `dsh-client-ui-skill`; every harness package declares
it, and the client type-assembly rename dropped it from both. The commands
manifest ships `src` alongside its generated typert faces, matching the
`./src/*` export it already declares.

knip gains the two directory-picker surface workspaces, whose specs are `.tsx`
and matched no default pattern, and ignores `zod` in the commands workspace:
that dependency belongs to the generated Remote and Host faces in `lib/`, which
knip never scans. The unused `dsh-client-test-runtime` and
`dsh-client-connection` dev dependencies are gone; the picker surface's own spec
never imported the former, and ui-settings reads the carrier's types through the
Remote assembly now.
