chore: clear the rustc 1.96 clippy lint that fails CI

Unrelated to this branch's change; main already fails clippy --all-targets -- -D warnings
without it, which is what failed the Windows integration job here. One
clippy::nonminimal_bool site in canvas.rs, taking clippy's own rewrite: the
negation stays outside, so the is_finite guards and their NaN behaviour are
unchanged. A sweep of all 30 workspace members found no other site.
