fix(code-runtime-python): restore the runtime's cross-package dependency declarations

The earlier merge had adopted master's protocol-only package.json (peer/dev
limited to invariants and cordis, no dependencies), but src/index.ts imports
@deepseek-ai/dsh-code-runtime, dsh-session, dsh-timeout, and schemastery at
runtime — a published lib/index.js could not resolve those bare specifiers.
The manifest now mirrors code-runtime-worker-thread (the five peers, the
schemastery dependency, and the matching dev set); the lockfile, module graph,
and third-party notices are regenerated, and the module-graph zh pair is
re-synced.
