The committed lockfile pinned tempfile 3.5.0, whose unix dependency path resolves to rustix 0.37.27. rust-lang/rust#155433 (merged 2026-05-03, first shipped in Rust 1.97.0) ripped out the `rustc_layout_scalar_valid_range_start`/`end` attributes in favour of pattern types (rust-lang/rust#135996). rustix 0.37.27's build script probes whether `#![feature(rustc_attrs)]` compiles and emits `cargo:rustc-cfg=rustc_attrs` when it does, which activates those attributes on `struct Errno` in src/backend/linux_raw/io/errno.rs. On rustc from nightly-2026-05-04 onward the probe still compiles but the attributes are rejected with: error: attributes starting with `rustc` are reserved for use by the `rustc` compiler so the build fails (rust-lang/rust#156510). The probe is rejected on stable channels (E0554), so only nightlies are affected. The 0.37 line has no fixed release; upstream fixed the master line in bytecodealliance/rustix#1663. This regenerates the lockfile so that tempfile resolves to 3.27.0 and rustix to 1.1.4. No Cargo.toml change is needed: the existing `tempfile = "3"` / `"3.5.0"` requirements already permit it. The MSRV (1.66.0) is unaffected: tempfile 3.27.0 declares rust-version 1.63, and the newly added wasm32-wasip2/UEFI-only dependencies (wasip2, wit-bindgen, r-efi) are never built for any supported target.

This bumps
tempfileandrustixin Cargo.lock to avoid the breakage introduced by rust-lang/rust#155433.The breakage happens because older versions of rustix used to use
#[cfg_attr(rustc_attrs, rustc_layout_scalar_valid_range_start(...))]and#[cfg_attr(rustc_attrs, rustc_layout_scalar_valid_range_end(...))]attributes. New versions don't anymore, so this bumpstempfileto a version that allows the newer semver version range ofrustix.
