Function emit_storage_controller_verilog 

pub fn emit_storage_controller_verilog() -> String

The dumb in-order executor: a countdown FSM. It loads the next word, waits exactly delta cycles, strobes the command pins, and acks the word — in arrival order, by construction (there is no other datapath). cmd_ack pulses on CONSUME (load), so the producer’s read index advances immediately (the classic handshake-latency trap avoided, exactly as in dram_executor).
