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

### Multik version

0.3.0

### Module

multik-openblas

### Platform

JVM

### Operating System

Linux

### Description

`NativeLinAlg.dot` for matrix-matrix 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 small integer ComplexDouble matrices with exact expected values and `assertEquals` — no tolerance. Failed in 3 out of 4 CI runs, making it the most frequently failing test.

### Reproducer

```kotlin
val matrix1 = mk.ndarray(
mk[mk[ComplexDouble(1, 2), ComplexDouble(3, 4)],
mk[ComplexDouble(2, 3), ComplexDouble(4, 5)],
mk[ComplexDouble(3, 4), ComplexDouble(5, 6)]]
)
val matrix2 = mk.ndarray(
mk[mk[ComplexDouble(9, 8), ComplexDouble(7, 6), ComplexDouble(5, 4)],
mk[ComplexDouble(8, 7), ComplexDouble(6, 5), ComplexDouble(4, 3)]]
)

val actual = NativeLinAlg.dot(matrix1, matrix2)
assertEquals(expected, actual) // Fails intermittently
```

### Additional information

```text
Flaky — failed in 3/4 CI runs.
All failures are AssertionFailedError at NativeLinAlgTest.kt:134.
CI runs: 22511673326, 22511741037, 22511767151.
Environment: Ubuntu 22.04.5 LTS, gcc-12 (12.3.0), g++-12, JDK 21 Temurin, x86_64.
```

Start with NativeLinAlgTest.kt:134 and run the ComplexDouble matrix-matrix dot test using the reported Ubuntu, gcc-12, and JDK 21 environment. Trace the NativeLinAlg.dot path in the multik-openblas module and compare repeated runs with the provided reproducer; done means the expected exact result is returned consistently without intermittent CI failures.
