feat(ecstore): add runtime-probed io_uring read backend, gray-off by default (rustfs/backlog#1104) Wire the standalone rustfs-uring crate (https://github.com/rustfs/uring) into LocalIoBackend as an opt-in read backend. When RUSTFS_IO_URING_READ_ENABLE is set AND the per-disk io_uring probe succeeds, positioned reads go through the cancel-safe UringDriver; otherwise — default, or on a restricted host, or on any per-read driver error — reads fall back to StdBackend byte-for-byte, so the default build is unchanged. - Cargo.toml: rustfs-uring as a Linux-only git dependency (pinned rev). The guard scripts/check_no_tokio_io_uring.sh allows an explicit io-uring integration; only the tokio "io-uring" runtime feature is banned. - UringBackend mirrors StdBackend::pread_bytes's resolution/access/bounds preamble and only swaps the raw byte read; the other three trait methods delegate to the inner StdBackend. - Backend selection at LocalDisk construction via build_local_io_backend. - Differential test uring_backend_reads_match_std: with the flag set, every positioned read returns byte-identical data (driver-served when io_uring is available, StdBackend fallback otherwise). Verified: cargo check -p rustfs-ecstore on Linux; the differential test passes under real io_uring (seccomp=unconfined). The runtime errno degradation latch, per-disk probe cache, and productionization are tracked in rustfs/backlog#1101/#1102. Co-authored-by: heihutu <heihutu@gmail.com>
