/**
 * Execute WASM in a Web Worker with timeout enforcement.
 *
 * Creates an inline Web Worker via Blob URL that runs a minimal WASM executor.
 * If execution exceeds the timeout, the worker is terminated.
 *
 * **Limitation**: The Worker sandbox includes only basic host functions:
 * print, string ops, int/float_to_string, panic, exit, random_int, time_now.
 * Programs using crypto, HTTP, file IO, or other domain builtins should use
 * `runBrowserDirect()` instead, which has the full host import set via
 * `createHostImports()`.
 *
 * **Note**: Requires a browser environment with Web Worker support.
 * In environments without `Worker` (e.g., Node.js vitest), falls back to
 * `runBrowserDirect()`.
