💡 Pulsar Magnetosphere — 2D Light Cylinder and Pulse Profile

2D companion of the pulsar magnetosphere sim: dipole field lines with the light cylinder, open and closed zones, polar-cap size, Goldreich-Julian density, vacuum-dipole spin-down with period derivative and characteristic age, and the pulse profile for a chosen viewing angle. Checked by RK4 field-line tracing and a numerical spin-down integration.
