/**
 * Synthesizer for JavaScript `Set` objects.
 *
 * Dehydrated format:
 *   [["a", "b", "c"], { "s": "set" }]
 *
 * The set is stored as a plain JSON array of its values. Values are stored
 * as-is, so only JSON-safe primitives (string, number, boolean, null) are
 * guaranteed to round-trip perfectly. Complex values inside the set are not
 * recursively processed — the SnapshotManager handles top-level synthesis only.
 *
 * If you need a Set of complex types, use a custom synthesizer instead.
