ci: make just lint the single source of truth for clippy

The nightly-2026-06-10 bump (#1725) added allows for new clippy lints
(unused_async_trait_impl, useless_borrows_in_formatting) to the CI
clippy command only, so local just lint failed on the vendored
rolldown crates.

Move the allow flags into the just lint recipe and have CI run
just lint, so there is no second copy to keep in sync.
