/**
 * Format a v2 query result into a plain string for LLM context injection.
 *
 * The canonical string rendering lives on the APPLICATION LAYER: every /query
 * response body carries `llm_prompt`, the whole result rendered as a Markdown
 * document by the server (the same code on every surface). When this helper
 * finds it, it returns the server's string verbatim. The client-side
 * formatting below is only the legacy fallback for responses from servers
 * that predate `llm_prompt`.
 *
 * Accepts:
 * - 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));        // the server-rendered llm_prompt, verbatim
 * ```
