Details 
- Drop support for Python 3.8.
- Bump minimum dependencies to `numpy>=2.0` and `numba>=0.60`.
- Replace legacy NumPy polynomial functions (polyder, polyadd, etc.) with
  the modern `numpy.polynomial.Polynomial` class for stable calculus and
  arithmetic operations.
- Remove `_strip_leading_zeros` as the modern API handles degree alignment
  and zero-trimming natively.
- Retain highest-to-lowest `self.coefficients` array to maintain compatibility
  with Numba and CUDA GPU kernels evaluating via Horner's method.
- Fix `TypeError` in `quadratic_solve` by evaluating `b.real >= 0` to safely
  support complex coefficients.
- Update `quadratic_solve` return type hint to `np.ndarray`.
