refactor(sign/verify): split boolean param into dedicated setSignSpec/setVerifySpec overload Separate the boolean parameter into its own method overload (SetSignSpecBoolean/SetVerifySpecBoolean) instead of using a combined OptIntUint8ArrBool union type, improving type safety and API clarity. - Rename OptIntUint8ArrBool to OptIntUint8Arr (drop BOOLEAN variant) - Add SetSignSpecBoolean/SetVerifySpecBoolean for boolean params - Update .d.ts type definitions with separate boolean overload Signed-off-by: kang1024 <yangjiankang3@huawei.com> |
