Detailed Description

EngineWrapper interface backed by a precomputed engine performance LUT.

Loads .npz from generate_controller_lut (engine-only mode). Axes: P_u_fuel, P_u_ox.
Outputs: F, MR, P_ch, mdot_F, mdot_O, injector_dp_F, injector_dp_O, stability_score,
injector_stiffness_ok.

		float	P_d_F,
		float	P_d_O,
		bool	use_cache = True )

Estimate engine performance from tank/ullage pressures via LUT lookup.

Parameters P_d_F, P_d_O are tank pressures (P_u_fuel, P_u_ox).
