Trait StateBackend 

pub trait StateBackend:
    StateBackendCore
    + StateBackendQuery
    + StateBackendRunner { }

State backend interface — persistence of invocations and results.

Mirrors pynenc’s BaseStateBackend. This is a composite trait combining three sub-traits:

• StateBackendCore — invocation/result/history storage, cleanup, introspection
• StateBackendQuery — workflow queries, workflow discovery, workflow data
• StateBackendRunner — runner context, runner analytics, time-range queries

Implementations should implement the sub-traits directly. This supertrait is auto-implemented via a blanket impl.
