vectorialcalculus 2.0.0

Breaking changes

• The public interface uses the vc_ prefix and replaces the 47 export names from 1.0.5. Existing calls require migration. The installed legacy-map.csv lists recovery destinations and key differences.
• Calculation and visualization have separate interfaces. Plotting is optional and uses plotly.

Features

• Numerical differentiation, integration, and multivariable calculus with diagnostic results.
• Spatial curves, vector fields, line and surface integrals, and numerical comparisons for Green, Stokes and Gauss.
