test(08-10): cover data-system/data-state gap codes and add loader tests

- eventDispatch: assert codes 171 (missing event id) and 172 (non-boolean reduce result)

- path/system: assert code 182 when binding a foreign CoreState layer

- data-state event: assert code 1001 for an unknown setBlock tile

- loader: new loader.test.ts covering PrefixedJSONCProcessor 66/67, DefaultDataLoaderHook 69/success, and MotaDataLoader public surface (66/67/68/69; 68 recorded unreachable)
