Drop the deleted `@deepseek-ai/dsh-client-runtime` from dsh.client.inject
and remove the preloaded-client-externals channel that died with it; mirror
0.1.2's platform module table (+ dsh-client-store) in the client bundle's
purity gate; widen the dsh peer ranges to >=0.1.0-rc.7 so 0.1.2 prereleases
resolve; pin the devDependency types to the newest published surface
(0.1.1-rc.2); the bundle smoke's fake ctx now honors inject callbacks.
