Detailed Description

Layer 3: Thermal Protection Optimization (Final Sizing)

This layer optimizes final ablative liner and graphite insert thicknesses to
meet recession requirements with margin while minimizing mass.

Once Layer 2 passes, this refines the thermal protection to right-size
the thicknesses (20% margin over max recession).

Run Layer 3: Thermal Protection Optimization.

Optimizes final thermal protection thicknesses to meet recession requirements
with margin while minimizing mass, while preserving the Layer 2 burn
quality (impulse, stability).

Args:
    optimization_method: Optimization algorithm to use:
        - "gradient": Fast gradient descent (recommended). Exploits monotonic
          relationship between thickness and recession. ~5-10 evaluations.
        - "cma": CMA-ES global optimizer. More thorough but slower. ~60-80 evals.
        - "de": Differential Evolution fallback. Similar to CMA-ES.

Returns:
    Tuple of (optimized_config, updated_time_results, thermal_results)
