The vendored January tree did not parse at all on a current nightly: 36 errors in iris-core, all from one syntax change. `impl const Trait for T` is now `const impl Trait for T`, with generics on the `impl`. Bounds are unaffected, and the traits were already declared `const trait` -- so the diagnosis recorded in RUST.md was wrong, and pinning back to a January nightly would only have deferred this. Everything else (the unresolved UiVec2/Vec2/impl_op imports, a Color<u8> resolving to wgpu_types::Color) cascaded from the seven files that failed to parse. The pin is dated rather than `nightly` because that is exactly the failure: a rolling channel moving under a build Dev Updater runs unattended. It carries the components and Android targets too, so a fresh clone provisions itself. Also drops two `#![feature]` gates the compiler reports as declared and unused, since the build stays warning-clean, and takes rustfmt's import order in attr.rs.
