Module exec 

EX-stage execution: Decoded plus operands in, result out (T-11-002).

The bridge between crate::decode and crate::alu. Kept separate from the pipeline so it stays a pure function of (op, rs_val, rt_val, hi, lo) — testable without a machine, and with no way to accidentally read register state the decode did not name.
