Commit Message

test(bigint): fix shr whitebox test that silently constructed 0

The `RADIX * RADIX / 2` operand overflowed UInt64 (RADIX = 2^32, so
RADIX * RADIX = 2^64 wraps to 0), making the test build a = 0 and shift
that — exercising none of the multi-limb right-shift path it intended.
Construct 2^63 directly as a BigInt (1N << 63): it spans two 32-bit
limbs and still shifts to 0 under >> 64, so the assertion is unchanged
but now meaningful. Surfaced by Copilot review on #3681.
