Fix BigInt exponentiation bypassing execution constraints#2350
Merged
Conversation
…os#2349) Validate estimated result size before calling BigInteger.Pow to prevent memory exhaustion from inputs like 11n**711111111n. Limits result to ~1 million bits (~125 KB), throwing RangeError for excessive sizes. Also fixes missing negative exponent check in **= assignment operator.
