fix(windows-host): rustfmt pf_vdisplay.rs + Cargo.lock for the new host deps

1a86f16 shipped the agent-written pf_vdisplay.rs unformatted (cargo fmt --all --check
gate) and omitted the Cargo.lock edges for the new windows-only deps (pf-vdisplay-proto +
bytemuck). cargo fmt --all is now clean; Cargo.lock records the host dep edges.
