feat(python-runtime): package the dsh CLI and profile assets

Make the zero-code dsh-python-runtime-closure depend on the real @deepseek-ai/dsh application and every required profile peer, then package apps/cli's built bin instead of the deleted Python carrier. Rename executables to deepseek-harness-sdk-runtime-<platform>-<arch>, update wheel/platform/build workflow discovery, and install a Python dsh console command that requires explicit DSH_HOME before exec.

Include profile, bundle, preset, native addon, and shared-library assets needed by the full CLI. Remove the checked-in default cordis.yml and preserve the existing wheel distribution names, Python module names, sidecar validation, and wire identity. Runtime resolution and release tests pin the new artifacts and dev Node carrier.
