The Blaxel and Daytona drop-ins honour the create options they used to drop
In withruntime.blaxel, SandboxInstance.create(config, timeout=N) (1 to 50 seconds, as Blaxel 0.4.13) deletes a sandbox not running in time and raises SandboxCreationTimeoutError, and safe=True checks the new sandbox answers. In withruntime.daytona, create(timeout=...) bounds the create, queue_timeout is how many minutes it waits for room (then DaytonaQueueTimeoutError), pip_install_from_requirements takes pip's index and link options, and kvm, a dockerfile_commands build context and wait_for_resize_complete are refused by name instead of ignored.
