 Global constraint ensuring that the tuple `x` does not match any configuration listed within the conflict set `pair_vars`. This constraint, originating from the extension model, stipulates that `x` must avoid all configurations defined as conflicts: `x ∉ pair_vars`. It is useful for specifying tuples that are explicitly forbidden and should be excluded from the solution space.
