Function nudged_dimension 

fn nudged_dimension(value: u32) -> u32

The one transient intermediate size the nudge strategy resizes to before restoring the real size, to provoke a fresh compositor configure event. Grow by 1px so the size genuinely changes (a no-op resize is coalesced away); if the window is already at the u32 ceiling, shrink instead so the value still differs.

Pure so the “which size forces a configure” decision is unit-testable without a windowing system; the actual set_size FFI stays in apply_wayland_fix (Linux-only, so not linked here).
