/**
 * `JSON.stringify` with deterministic key ordering at every level.
 *
 * Required because object key order is preserved by `JSON.stringify`, and we
 * don't want `{ a: 1, b: 2 }` and `{ b: 2, a: 1 }` to hash to different keys.
 *
 * This is critical for cache key generation when comparing messages restored
 * from different storage backends: jsonb columns (e.g. mastra_workflow_snapshot
 * in PostgreSQL) normalize key order, while text columns (mastra_messages)
 * preserve insertion order. Without stable stringification, functionally-equal
 * data-* parts produce different cache keys, causing false dedup misses.
