Fixes #318.
Use unsigned shift operands in mask operations and bound extended hash indices to
RHASH_HASH_COUNT. The hash-check bit-length helper now rejects zero before callingctz, avoiding an invalid shift reached by the existing missing-files case.Validation: Linux/GCC 13.3 UBSan build; all 26 full CLI groups pass, including the missing-files case. The original UBSan report identified
ctz(0)and the following oversized shift.
