jsvalue_to_json 串值分支原经 to_owned_string（lossy）后按 char 流序列化：孤立
surrogate 单元被打成 U+FFFD 且输出裸非法码单元（非 well-formed JSON，
JSON.parse 无法复原同值）。现按单元流序列化（stringify_string_units）：良配
代理对原样输出 astral 字符，非配对孤立 surrogate 输出 \\uXXXX（well-formed
JSON 要求，round-trip 复原同值），C0/C1 控制码输出 \\uXXXX，其余按 JSON
转义规则。
toJSON/replacer 键参数同改：键 si 物化为单元序列（整数键 → ASCII 数字串，
字符串键 → 码表键经 decode_key 还原含孤立 surrogate 单元），new_string_units_owned
建参——与 0c750fa 键物化面（Object.keys/ownKeys/entries/Reflect.ownKeys/json
reviver 键同源）口径一致，replace/reviver 键参数不再走 lossy 串值。
三并钉：json_tests 增补 stringify 孤立 surrogate round-trip / 代理对 astral
直出 / 键面单元传递三则；JSON 套件 37/0，node 13 用例对照一致。
