feat: BigInt.prototype[Symbol.toStringTag] = "BigInt"
...
Adds the well-known @@toStringTag data property (writable:false,
enumerable:false, configurable:true) so Object.prototype.toString and
property descriptors match the spec. Remaining built-ins/BigInt failure
(Symbol.toStringTag.js verifyProperty) is blocked on String(Symbol)
support in the Symbol track.

fix: BigInt SUB/MUL with 0n no longer raise Division by zero
...
binary_arith! applied an unconditional is_zero() guard, so x - 0n and
x * 0n (and wrapped-object variants) incorrectly threw RangeError.
Only DIV/MOD legitimately reject BigInt zero divisors; SUB/MUL must
compute normally. test262 language/expressions/subtraction:
29/6 -> 30/5 (bigint-arithmetic now passes).
