Smaller flag issues found while reviewing the lifter, grouped since each is a line or two:
CPL uses flags="*", but it only sets H and N.SCF / CCF do not touch H or N.LD A,I / LD A,R set no flags; they should set S and Z, clear H and N, and copy IFF2 into P/V.RETI / RETN do not model IFF1 <- IFF2.CPI / CPD write only Z.pv is mapped to OverflowFlagRole, so parity after logic ops is modelled as signed overflow (there is already a TODO about this in the source).
