/**
 * Maps TORUK Core's persisted messages onto the widget's runtime message shape.
 *
 * Core is the only source of chat history, so this is the single place where a
 * stored message becomes a rendered one. Field names follow Core's
 * MessageOutputDto exactly — note `createdDate` (not `createdAt`) and `role`
 * carrying the engine's own 'userMessage' / 'apiMessage' values.
 *
 * The engine passthrough fields are stored as JSON strings. They are parsed
 * defensively: a single malformed field drops that field, never the message.
