Hojun-Cho d456263f7e test/wcc/data: grow the declarative compiler corpus to 1,224 fixtures
The r-prefixed waves absorb the runtime, reject, and byte-compare rows
of the migrated native carriers; each fixture is one directory with one
case.ww and a //ww:error, //ww:compile, //ww:run, or //ww:run-exit
directive covering both frontends.
