Subject: [PATCH] fix: use integer dtype for random_seed in query script

The standalone query script passed random_seed as np.single (float), but

the Triton input spec and the streaming variant use np.int_. This could cause

type mismatches when the model expects an integer seed.

Adds a unit test that mocks pytriton and verifies the dtype is np.int_.
