offload-run

Drive a remote Sprite (Fly.io stateful sandbox) so build / test / serve work never burns local CPU/RAM. offload <subcommand>. Default is run, so offload -- npm test runs your command in the cloud, streams stdout/stderr, and returns the exit code unchanged — it behaves like a local run.

Per project, everything maps to one ephemeral run sprite offload-<type> keyed to a dependency-warm golden checkpoint (deps installed once, restored each run in seconds — no reinstall). Servers get a separate persistent sprite offload-srv-<dir> so a run never wipes them.
