refactor(sdk): name the private Python runtime carrier explicitly

Rename the relocated npm workspace to @deepseek-ai/dsh-sdk-python-runtime and the runnable example to python-sdk-agent, then update every owning English/Chinese document, test, and packaged-runtime reference. Remove the obsolete standalone bin while retaining the carrier entrypoints used to assemble the wheel runtime.

This is intentionally a naming and ownership change, not a Python SDK migration. The public deepseek_harness_sdk and deepseek_harness_runtime module, wheel, executable, environment, and wire behavior remain unchanged. Documentation records that this private carrier is the temporary sole non-dsh application exception and will move to profile launch later.
