Catch `ResourceExhaustedError` from `Sandbox.create()` on SDK 1.6.0 and later\n\n### Runloop Devboxes\n\n1. Set an idle policy (`idle_time_seconds` with `on_idle: suspend`) so a forgotten devbox stops billing compute\n2. Route outbound API calls through an agent gateway instead of putting keys in the devbox environment\n3. Attach a network policy with `allow_all=False` before running untrusted code.
