Documented steps

Create a sandbox with `Sandbox.create()` (E2B_API_KEY required).
Run a command: Python `result = sandbox.commands.run('ls -l')`; JS/TS `const result = await sandbox.commands.run('ls -l')`.
Read output from `result.stdout` (and `result.stderr` for errors).
For streaming chunks in JS pass an `onStdout` callback to `commands.run`.
Kill the sandbox when done with `sandbox.kill()`.

Known gotchas

commands.run executes a real shell command - do not interpolate untrusted input into the string; pass values via `envs` and reference `$VAR` instead.
Very long commands can hit the command/sandbox connection timeout; raise the timeout for long-running jobs.
You can install packages first (e.g. `sandbox.commands.run('pip install requests')`) before running code that needs them.
