refactor(semver): change ConstraintInterface to a closed enum

Replace the dyn ConstraintInterface trait objects with an AnyConstraint
enum closing over its four implementors (Simple, Multi, MatchAll,
MatchNone), mirroring the earlier Rule enum conversion. Rename
constraint.rs to simple_constraint.rs to match the renamed Constraint
type.
