Chinesezjc 4674d8fa92 fix(code-runtime-python): verify union<->roster both ways, stop pycache writes, refresh metering prose
Address the latest review round:

- WireFrameShapesCoverUnions checked only union ⊆ roster, so removing a frame
  from a message union (e.g. dropping ReplyErr from ReplyMessage) left the check
  true while the public TS union diverged from the wire. Replace it with a
  bidirectional equivalence between MessageFrames and the roster's message-frame
  value types (nested Namespace/ErrorClass/DoneErrorField excluded): both a frame
  added to a union without a roster entry and a frame removed from a union now
  fail typecheck (both verified).
- The mirror e2e's python3 probes imported protocol.py without -B, writing
  py/__pycache__/*.pyc into the (un-ignored) source tree. Add -B to both.
- Refresh the metering prose (checkDoneValue JSDoc + README both sides + Agent
  Note both sides): the incremental-work list no longer says "per-key
  JSON.stringify" now that jsonStringBytesUpTo scans without stringifying;
  re-record the README and Agent Note i18n pairings.

code-runtime/ — code-execution capability family

English | 中文

The code-execution capability seam (see capability seams): an abstract runtime interface for executing one model-written program against host-provided async bindings, capturing what it printed and returned. The consumer is the tool registry's Code Mode (tools: { mode: code } — the run_code tool and the SDK generated in the loaded runtime's language); design in the Code Mode Agent Note. Product packages.

Package Role ctx key
code-runtime/ Code-execution seam and shared vocabulary ctx.codeRuntime
code-runtime-worker/ Worker-thread backend registers ctx.codeRuntime

Backends register the seam without changing its consumer. The child READMEs own language, isolation, and execution-budget details.
