Pull Request Overview
This PR fixes the complex dot product formulation in the stdlib intrinsics implementation to ensure compliance with the mathematical standard. The fix addresses issue #1016 by correcting the conjugation logic in complex number multiplication.
- Modifies the complex dot product implementation to conjugate the first vector instead of the second
- Updates both the standard and Kahan summation variants of the dot product functions
- Adds comprehensive test coverage to verify conformance with the compiler intrinsic behavior
