CUBELinux-2

- DaemonBackend::put/get now round-trip the FULL record envelope (header+body) verbatim via rawput/rawget instead of stripping to a bare body. Before this, a socket-backed mount wrote the bare body but get returned it as if it were a record, breaking the FUSE read-back path (get_record could not decode it). This diverged from the in-memory backend and silently corrupted reads. - Cargo fmt --check now passes (was failing; the committed tree was never a clean ./check, which is why the durable mount could regress undetected). - Fix two new clippy lints (manual_is_multiple_of) in cubefs/backend.rs and cubesys/commands.rs so the -D warnings gate is green. - Daemon-backed integration tests (cubefs_daemon_smoke, daemon_backend_smoke) now use the real CubeStore<DaemonBackend> record path and are #[ignore]d so the default gate (no daemon) stays green, while ./check daemon spins up a live cube-server and runs them via --ignored. This makes the durable-socket contract an actual enforced test, not a manual ad-hoc script.
