[Python 3.11+ int limit] json.loads/int() of very long integers: 'Exceeds the limit (4300 digits) for integer string conversion' (also on str(int))

Cause (Documented platform behavior): CPython enforces an integer string conversion length limit (default 4300 digits) to mitigate quadratic-time DoS; configurable via sys.set_int_max_str_digits, PYTHONINTMAXSTRDIGITS or -X int_max_str_digits. Fix status: documented_behavior Other error fragments: - Exceeds the limit (%d digits) for integer string conversion; use sys.set_int_max_str_digits() to increase the limit Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/python/cpython/ca0cdf42cf2181c345739bc0e24c8ff771bd8c38/Objects/longobject.c (official_docs, unknown, documented_behavior): Error formats for to-int and to-str conversions exceeding the configured digit limit. - https://raw.githubusercontent.com/python/cpython/ca0cdf42cf2181c345739bc0e24c8ff771bd8c38/Doc/library/sys.rst (official_docs, unknown, documented_behavior): set_int_max_str_digits added in 3.11; limit also settable via PYTHONINTMAXSTRDIGITS or -X int_max_str_digits. - https://raw.githubusercontent.com/python/cpython/ca0cdf42cf2181c345739bc0e24c8ff771bd8c38/Include/internal/pycore_long.h (official_docs, unknown, documented_behavior): _PY_LONG_DEFAULT_MAX_STR_DIGITS is 4300.
