style: cargo fmt --all (rustfmt 1.96.0 drift across the re-arch branch)

`cargo fmt --all --check` (ci.yml) was red on main: the client re-architecture
commits and origin's windows-shortcut commit landed with rustfmt violations
(e.g. a 104-char .with_context line in hyprland.rs, an unsorted mod block in
vdisplay.rs, the input.rs `{`-placement CI flagged). Reformat the tree so the
fmt gate passes; no functional changes.
