Flaky: NativeLinAlg.dot matrix-vector ComplexDouble returns wrong result on Linux

### Multik version

0.3.0

### Module

multik-openblas

### Platform

JVM

### Operating System

Linux

### Description

`NativeLinAlg.dot` for matrix-vector multiplication with `ComplexDouble` produces incorrect results intermittently on Linux (Ubuntu 22.04.5 LTS, gcc-12 12.3.0, JDK 21 Temurin). The test uses a 2x2 ComplexDouble matrix and a 2-element vector with exact integer expected values. Failed in 2 out of 4 CI runs.

### Reproducer

```kotlin
val matrix = mk.ndarray(
mk[mk[ComplexDouble(1, 2), ComplexDouble(3, 4)],
mk[ComplexDouble(5, 6), ComplexDouble(7, 8)]]
)
val vector = mk.ndarray(mk[ComplexDouble(1, 0), ComplexDouble(0, 1)])

// [1+2i, 3+4i] . [1+0i, 0+1i] = (1+2i)*1 + (3+4i)*i = 1+2i + 3i-4 = -3+5i
// [5+6i, 7+8i] . [1+0i, 0+1i] = (5+6i)*1 + (7+8i)*i = 5+6i + 7i-8 = -3+13i
val expected = mk.ndarray(mk[ComplexDouble(-3, 5), ComplexDouble(-3, 13)])

val actual = NativeLinAlg.dot(matrix, vector)
assertComplexFloatingNDArray(expected, actual) // Fails intermittently
```

Start with the failing case around NativeLinAlgTest.kt:256 and reproduce the 2x2 ComplexDouble matrix-vector call described in the issue on Linux. Trace NativeLinAlg.dot through the multik-openblas module and compare intermittent results with the expected [-3+5i, -3+13i]. Done means the test is deterministic and passes in the reported CI environment.
