//!
//! Complete implementation of 7 foundational quantum algorithms from first principles.
//! Includes full mathematical verification, test coverage, and integration with the
//! QATAAUM quantum simulator ecosystem.
//!
//! **Algorithms Implemented:**
//! 1. Hamiltonian Pauli Sums - foundation for VQE/QAOA
//! 2. Variational Quantum Eigensolver (VQE) - hybrid optimization
//! 3. Quantum Approximate Optimization Algorithm (QAOA) - combinatorial optimization
//! 4. Hamiltonian Simulation - time evolution via Trotter-Suzuki
//! 5. Amplitude Estimation - quantum signal processing
//! 6. Quantum Walks - graph exploration and mixing
//! 7. Shor's Algorithm Modular Arithmetic - factoring foundation
//!
//! Clean-room implementation based on standard quantum mechanics and algorithms textbooks.
