maude: owise (otherwise) equations (8 tests, 229 total)

Parser reads trailing eq attributes (eq L = R [owise] .) via mau/split-attrs.
mau/crewrite-top is two-pass: ordinary equations first, owise last — an owise
catch-all fires only when no ordinary equation applies, regardless of
declaration order. Verified a catch-all declared first still defers.
