LoRA/QLoRA configuration optimizer and memory planner.

This crate provides tools for:

• Optimal LoRA configuration based on memory constraints
• Memory planning for different fine-tuning methods
• Adapter merging and inspection

Toyota Way Principles

• Heijunka: Memory planner levels resource allocation
• Kaizen: Iterative configuration refinement
• Muda Elimination: Optimal rank selection avoids wasted parameters
