Increase the boot-time flattened device-tree buffer from 2 KiB to 4 KiB so the root disk, install disk, console, entropy, network, and virtiofs devices fit together. Enable OverlayFS in the wasm defconfig and regenerate the minimal defconfig through olddefconfig and savedefconfig. TMPFS_XATTR remains unavailable because wasm is NOMMU and its TMPFS dependency requires SHMEM/MMU. Agent-Session: codex:019fe4bc-be37-76d2-84ac-6064346b040c
