fix(generator): don't abort the build on unmatched generation titles (#86)

seedGenerations called require(unmatchedTitles.isEmpty()), so the whole DB
build failed whenever generations.csv (ForDB) referenced a book missing from
the current otzaria-library — an upstream drift between the two sources. Keep
every generation link that matched and log a warning for the rest instead.
