FEAT: hypot ufunc implementation

[SwayamInSync]

Copilot Summary

This pull request adds support for the hypot (Euclidean norm) operation to the quad-precision NumPy extension, including both implementation and comprehensive tests. The changes ensure that the hypot function is available for quad-precision and long double types, is registered as a universal function (ufunc), and is tracked in the release documentation.

Quad-precision and long double hypot implementation

• Added the quad_hypot and ld_hypot functions to ops.hpp, providing quad-precision and long double implementations of the hypot operation using Sleef_hypotq1_u05 and the standard library hypotl, respectively. [1] [2]

Ufunc registration

• Registered the new hypot operation as a binary ufunc in umath/binary_ops.cpp, making it available to users via NumPy.

Release tracking

• Updated release_tracker.md to mark hypot as implemented and tested, ensuring the documentation reflects the new functionality. [1] [2]

Testing

• Added a comprehensive parameterized test for the hypot ufunc in test_quaddtype.py, covering basic cases, symmetry, zero, negative values, infinities, and NaNs to ensure correctness and robustness.
