chore(v1.1.8): cargo fmt --all (reviewer)

8 files needed re-wrapping after the F2 clippy-fix pass landed
un-fmt'd. Pure cosmetic — no behavioral change. Re-runs of
`cargo fmt --all -- --check` now exit clean.

Reviewer-supplied per REVIEW.md §7; folded onto the branch
to avoid a NEEDS-CHANGES round-trip on a purely mechanical fix.
