DiscussionState

Folded state for a discussion session.

participant_order is snapshotted at initial_state so fold can compute the next speaker without access to SessionMetadata (the adapter Protocol passes only state + envelope into fold). The hub's hydrate() re-folds from the WAL, which is deterministic because initial_state reads the same metadata.participants snapshot every time.
