Wilder's smoothing (RMA): seed from the first complete finite window,
then (prev * (period - 1) + v) / period. Valid scalar defaults retry
nonfinite seeds, leave a gap for missing inputs and retain seeded state.
Running overflow is unavailable without restarting. Supplied skip seeds from period
finite observations and holds state across gaps. propagate clears state on
a missing input and reseeds after period consecutive finite observations.
Warmup is NaN. The option path requires a positive safe-integer period and
valid policy, throwing RangeError or TypeError respectively.
