chore: let QEMU choose the disk I/O backend unless DISK_IO is set - #8

Conversation
2.0.1 forced DISK_IO=native. The compose file now passes DISK_IO through empty, so QEMU picks (io_uring on recent kernels), and hosts with a kernel before 5.12 set DISK_IO=native in .env, as documented in .env.example and the README.

Current Behaviour
Since 2.0.1
docker-compose.ymlforcesDISK_IO=nativefor every host, trading the faster io_uring path on recent kernels for a guaranteed boot on kernels before 5.12.Expected Behaviour
docker-compose.ymlpassesDISK_IOthrough empty unless it is set in.env, so QEMU chooses the backend (io_uring on recent kernels)..env.exampleand the README table document the three values and tell users on kernels before 5.12 (Ubuntu 20.04) to setDISK_IO=native, since those fail at boot withFailed to initialize io_uring.docker compose configresolves to an empty value when unset and tonativewhen set in.env.
