 *
 * All listeners are attached synchronously before any await to prevent
 * missed events from fast-completing processes.
 *
 * @param command - The binary to spawn.
 * @param args - Arguments to pass to the binary.
 * @param options - Timeout, abort signal, and ENOENT handling options.
 * @returns An async generator yielding StreamChunks followed by a final ExecutionResult.
