Module stack 

Stack scheduling for EVM code generation.

This module handles the translation from MIR’s SSA values to EVM’s stack-based model. The key abstraction is StackModel, which tracks which MIR values are at which stack depths.

Submodules

• model: Core stack model tracking value positions
• scheduler: Stack scheduler for generating DUP/SWAP sequences
• shuffler: Optimal stack layout transitions (backward analysis)
• spill: Spill management for values beyond depth 16
