feat(client): add the dsh-client-test-runtime package

A jsdom slot test runtime for feature specs: a real Cordis Context, the production SlotsService and web-react renderer, and typed session/workspace doubles (TestSessions implements ISessions with FixtureSession sessions; TestWorkspaces implements IWorkspaces), so the compiler flags fixture drift when a production face changes. Fixtures feed plain data: list rows, conversation snapshots, and ISession-typed behavior stubs; provide-bundle materialization runs the shared SessionProvideChannel. DOM snapshot support: declare()/renderSlot() mount a single slot inside a data-slot wrapper for local .snap capture, and a snapshot serializer folds CSS-module class hashes to their semantic locals and collapses svg internals to a content fingerprint. The typed provide() constrains declared-service fakes to Partial of the service's outward face.
