GenDurable.Outcome (gen_durable v0.1.2)

The five step/handle outcomes from the spec §3, with shape validation.

{:next, step, state}        # transition, runnable, attempt := 0
{:replay, state, delay_ms}  # same step, runnable, attempt += 1, eligible_at += delay
{:await, signal_name, state} # park, awaiting_signal
{:done, result}             # terminal, done
{:stop, reason}             # terminal, failed

Step names and signal names are normalized to strings.
