Module residues 

Residue calculus and complex analysis

Implements residue computation, contour integration, and complex analysis operations for symbolic computation.

This module is organized into focused sub-modules:

• Core residue computation and integration (in mod.rs)
• Singularity classification (singularities.rs)
• Pole finding for various function types (pole_finding.rs)
• Helper utilities (helpers.rs)
