The gate was already red on main, in files no round since had touched.
`cargo fmt` reflowed one wrapped assert in the benilla-ui loader tests. Clippy's
1.98 set added four lints the tree does not satisfy: `doc_lazy_continuation`
on room_claim.rs's `2b.` item (indented, as it already renders), and in
benilla-extract `chunks_exact_to_as_chunks` on the MOGI walk,
`manual_checked_ops` on the census mean, and `needless_borrow` on the class
table call. Each takes the fix clippy names.
33 errors remain in benilla-world's lighting, static_gx, water_fx and liquid
trees, from the same lint bump; they are left for their own round rather than
folded in here.
Verified: cargo fmt --all --check clean; `cargo clippy --workspace
--all-targets -- -D warnings` now fails only in benilla-world.
