Manage Daytona sandbox lifecycle: start, stop, auto-stop / auto-archive / auto-delete intervals, TTL, resize and delete

Documented steps

1. Start a stopped sandbox with `sandbox.start()`; stop a running one with `sandbox.stop()`. Stop is ungraceful, so flush any state you care about first.
2. For sandbox classes that support pausing (VM sandboxes), use `sandbox.pause()` to preserve memory and `sandbox.start()` to resume. Container sandboxes instead use `sandbox.archive()`, which moves the filesystem to object storage.
3. Set `auto_stop_interval` (minutes of inactivity before automatic stop). If not set, the default interval of 15 minutes is used; `0` disables auto-stop so the sandbox runs indefinitely.
4. Set `auto_pause_interval` for pause-capable classes. If neither auto-pause nor auto-stop is set, non-ephemeral sandbox classes that support pausing default to an auto-pause interval of 60 minutes; `0` disables it.
5. Set `auto_archive_interval` for container sandboxes; the default is 7 days and passing `0` uses the maximum interval of 30 days rather than disabling archiving.
6. Set `auto_delete_interval` to a positive number of minutes after stop before deletion. `-1` disables the auto-delete functionality; `0` means the sandbox is deleted immediately after it is stopped.
7. Set `ttl_minutes` for a wall-clock lifetime that applies regardless of activity or sandbox state; `0` disables it. Reset the deadline later with `sandbox.set_ttl(...)` and refresh the activity timestamp with `sandbox.refresh_activity()`.
8. Use ephemeral sandboxes for one-shot agent tasks: they are automatically deleted when stopped and cannot have auto-pause enabled.
9. Resize with `sandbox.resize(Resources(cpu=2, memory=4, disk=8))`. CPU and memory can be increased on a running sandbox; decreases require the sandbox to be stopped, and disk can only ever increase.
10. Delete with `sandbox.delete()`, optionally waiting for full teardown before returning. Official docs: https://www.daytona.io/docs/en/sandboxes, https://www.daytona.io/docs/en/architecture, https://www.daytona.io/docs/en/limits
