irisandClaude Opus 5 caaa733caa Make iris build: pin a dated nightly and migrate const-trait impls
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.

# iris needs nightly (see the #![feature] list in core/src/lib.rs and src/lib.rs).
# The pin is dated rather than "nightly" because the const-traits feature set
# changes shape between nightlies: on 2026-09-04 the vendored January tree would
# not parse at all, because `impl const Trait for T` had become
# `const impl Trait for T`. A rolling channel turns that into a build that
# breaks unattended on whatever machine Dev Updater happens to build on.
# Advance this deliberately, with the feature list in RUST.md's I0b.
