bigint.nx

bigint.nx -- KAT GATE for the multi-precision integer primitives (syscalls.nx import chain). 2026-07-09: the bi_* primitives moved to nx_bigint_lib.nx (importable, zero-imports) -- this twin and nx_bigint.nx were code-identical and BOTH carried main(), making the primitives unimportable into any main-bearing binary. This file keeps the ORIGINAL smoke battery as the standing gate on the syscalls.nx chain (the syscall-module duality's other side); nx_bigint.nx gates the nx_syscalls chain.
