What changed in this PR
This intermediate merge from v0.1 expands the library’s mathematics support with complex numbers and matrices, alongside the existing arbitrary-precision integers and elliptic curves.
Changes:
- Adds complex arithmetic and functions, matrix operations, decompositions, and exact integer-matrix algorithms.
- Adds numerical regression tests covering decomposition identities, algorithm boundaries, and extreme magnitudes.
- Exposes the new modules, integrates documentation, and updates package metadata to version 0.0.29.
