Code-by-wire v0.1.49

Fixed

• A very large transcript no longer takes the app down or leaves a blank
  pane behind. A rollout past the ~512MB ceiling on a JS string cannot be
  read whole, and in Electron's main process that overflow is an
  uncatchable process abort rather than a throw — a 1.4GB Codex rollout
  killed the packaged app seconds into launch, and pnpm dev on every
  run. Every whole-file read that can be handed an arbitrary transcript
  path — both analytics scanners, the Codex telemetry cache reached from
  session sync, readTranscript and getToolResult — now checks the size
  first and degrades per file: the scanners record the file's mtime so it
  stops being pending and the pass can still settle, retrying only if it
  ever shrinks, and opening such a session reports it as absent so the
  transcript panel shows its empty state instead of a permanently blank
  pane re-polling every 1.5s. An oversized session's turns don't land in
  analytics; reading them in bounded chunks is follow-up work.
• Punctuation converted by a Chinese IME now reaches the terminal as the
  converted character instead of the physical key — typing 、 no longer
  sends \. Both terminals decline keystrokes for the whole composition
  window, so xterm can't finalize a live composition early and emit the
  raw key, and they decline unmodified ASCII punctuation on keydown so the
  keypress that carries the converted character still fires. Plain letters
  and punctuation still arrive exactly once, and Ctrl+C still sends
  SIGINT.
