Chinesezjc 4e0d77c1d6 fix(code-runtime-python): reserve the log array envelope byte, unblock SIGXCPU before re-raise ...

Addresses the review's two remaining code warnings and the three suggestions:
- Log ledgers (host and child) start one byte below the budget, reserving the
  serialized outer-array envelope (two brackets and n-1 commas over n entries'
  separators); the exact-zero test moves to maxLogBytes 104 and a new exact-limit
  case pins that maxLogBytes 5 admits ['a'] (5 bytes) while 4 truncates to the
  marker alone.
- die_if_cpu_exhausted unblocks SIGXCPU (pthread_sigmask SIG_UNBLOCK, captured at
  import, None-guarded for Windows) before re-delivering it, so a program that
  masks SIGXCPU, burns past the soft limit, and returns is still classified as a
  timeout; a regression test pins the masked path.
- ast.parse passes filename="<model>" so parse-time syntax diagnostics carry the
  same source label as compile and runtime tracebacks; the syntax-error test
  asserts the label.
- The NUL-escape test comments use the true six-byte JSON escape \u0000 instead
  of the caret notation; the README Known Limitations (en + zh) records that
  PID-reuse protection is inert on macOS; a combined-rebind regression test pins
  BaseException plus the traceback reporter rebinding together.
