/**
 * WASM-sandboxed JavaScript executor for code mode.
 *
 * Runs LLM-generated processing scripts against raw tool output in a QuickJS
 * WASM sandbox. The sandbox has NO filesystem or network access — only DATA
 * (the tool's response as a string) and console.log() for output.
 *
 * Usage:
 *   import { executeInSandbox } from "./sandbox.js";
 *   const result = await executeInSandbox(rawJsonString, userScript);
 *   // result.stdout contains only what the script console.log()'d
 *
 * The QuickJS WASM module is loaded once and reused across calls.
 * Each execution gets a fresh context (no state leakage between calls).

/**
 * Execute a JavaScript script in a WASM sandbox with DATA injected.

 * The script can:
 *   - Read `DATA` (string — the raw tool response)
 *   - Use `JSON.parse(DATA)` to parse it
 *   - Use `console.log(...)` to produce output
 *   - Use standard JS: loops, map/filter/reduce, string ops, Math, etc.
 *
 * The script CANNOT:
 *   - Access the filesystem
 *   - Make network requests
 *   - Import modules
 *   - Access Node.js APIs
 *   - Leak state between calls
 *
 * @param data - Raw tool response string (injected as `DATA` global)
 * @param script - JavaScript code to execute
 * @returns SandboxResult with stdout and size metrics
