Detailed Description

Comprehensive optimizer that solves for all pintle dimensions and chamber geometry.

Optimizes:
- Pintle injector: d_pintle_tip, h_gap, n_orifices, d_orifice, theta_orifice
- Chamber: A_throat, A_exit, Lstar, D_chamber
- Materials: ablative thickness, graphite thickness
- Feed system: tank pressures, COPV sizing

All coupled with flight simulation and stability analysis.
