fix(code-runtime-python): declare the dsh-code-runtime dependency

The manifest omitted @deepseek-ai/dsh-code-runtime although src/index.ts
imports CodeRuntime and the portable-identifier constants from it and the
tsconfig references ../code-runtime. A three-way package.json merge over
the protocol-layer stub dropped the entry; restore it in peer and dev
dependencies so the declaration matches the import.
