* cover all Radixor dictionary languages
* add PRIMARY_OUTPUT, ANY_CANDIDATE, and ALL_CANDIDATES policies
* measure pairwise over-stemming and under-stemming
* add balanced accuracy and complementary quality metrics
* compare single-output and multi-output stemmers fairly
* improve result validation, reporting, and documentation
* move stemming quality tests into the standard test source set
* preserve the existing JMH benchmark structure and badge output
test: add property-based tests for FrequencyTrie determinism across repeated compilation
test: verify semantic alignment of get(), getAll(), and getEntries()
test: verify binary serialization and compressed persistence round-trip stability
test: verify builder reconstruction preserves observable trie behavior
test: add property-based tests for PatchCommandEncoder encode/apply round-trip and determinism
test: add generated stemmer-trie properties ensuring returned patches reconstruct only acceptable stems
test: introduce bounded reusable jqwik generators and scenario builders for maintainable property coverage
build: add jqwik to test dependencies and integrate it with the existing JUnit Platform setup
test: replace Jupiter display and tag annotations in jqwik suites with jqwik-native metadata to remove discovery warnings
