Introduce @deepseek-ai/dsh-code-runtime-python with the versionless JSON-lines protocol between the Node host and the CPython subprocess: the host-side hostile-frame codec (validateChildFrame, encodeJsonPlain, checkDoneValue, hasUnsafeIntegerToken, hasNonLosslessNumber, logTruncationMarker) and the Python-side wire-vocabulary mirror (py/protocol.py). This is the protocol layer of the code-runtime-python stack, split from #436 and based on the multi-language seam extension. The PythonCodeRuntime implementation and its Python JSON codec land in the backend-core PR on top of this branch. Ship the minimal buildable package skeleton (package.json, tsconfig, tsdown, barrel index, invariant companion, bilingual README) because the workspace-constraint, coverage, and invariant-topology gates require the package to exist and build the moment its directory does; the backend-core PR extends those files rather than creating them. Align py/protocol.py with src/protocol.ts (the round-12 review of #436 found LogMessage.truncated, DoneMessage.error.kind, and Namespace.errorClass stale) and guard the two runtime-executed surfaces (PROTOCOL_FD and the log truncation marker) with a real-python3 cross-language mirror e2e test.
