Add Serialize/Deserialize derives to all public data types (ParamValue, Distribution, Direction, TrialState, ParamId, AttrValue, CompletedTrial) gated behind a `serde` feature flag. Introduce StudySnapshot struct and Study::save()/Study::load() for persisting and restoring study state as human-readable JSON.
