//! IR Spectroscopy module: numerical Hessian, vibrational frequencies, and IR intensities.
//!
//! Implements Phase D2 of the spectroscopy roadmap:
//! - Numerical Hessian via central finite differences (6N energy evaluations)
//! - Mass-weighted Hessian diagonalization for normal modes and frequencies
//! - IR intensities from numerical dipole derivatives along normal modes
//! - Lorentzian-broadened IR spectrum generation
