Spawn a subprocess and get buffered output

You can spawn subprocesses in a sandbox and get buffered output. For example, to print the current working directory as seen below. This is useful for running shell commands and scripts.

import { Sandbox } from "@deno/sandbox";

await using sandbox = await Sandbox.create();

const cwd = await sandbox.sh`pwd`;

For long‑running processes or large output, stream the stdout/stderr instead of buffering it all in memory.
