Chinesezjc f9ab1edc68 fix(code-runtime-python): meter escaped string bytes without allocating, bind frame roster to the unions ...

Two review findings on checkDoneValue's metering and the wire-mirror binding:

- The string/key byte check used a decoded-length lower bound and then called
  JSON.stringify, which materializes the ~6x escaped copy before the over-budget
  check — the hundreds-of-MB spike the metered walk exists to avoid. Add
  jsonStringBytesUpTo, a non-allocating scan that computes the exact escaped
  UTF-8 size (matching JSON.stringify byte for byte, including surrogate pairs
  vs lone surrogates) and bails the instant it crosses the remaining budget; use
  it for both string values and object keys.
- The frame roster in WIRE_FRAME_FIELD_ROLES was hand-written, so a frame added
  to ChildToHost/ReplyMessage without a roster entry slipped past. Introduce
  WireFrameShapes (name -> interface) as the canonical roster the roles map is
  bound against, plus a WireFrameShapesCoverUnions compile-time assertion that
  every message-union member appears in it (verified: adding a frame to a union
  without a WireFrameShapes entry fails typecheck).
