/**
 * Format a v2 query result into a plain string for LLM context injection.
 *
 * Accepts either:
 * - The full v2 envelope (`{ success, data, error, meta }`) — auto-unwraps `.data`
 * - A bare retrieval result (with `chunks` / `graphContext`)
 *
 * @example
 * ```typescript
 * const response = await client.query({ query: "...", tenantId: "..." });
 * console.log(buildString(response));        // works on the envelope
 * console.log(buildString(response.data!));  // also works on just the data
 * ```
