- Extract sense-level synonyms/antonyms from Wiktionary (not just top-level),
dramatically improving Portuguese synonym coverage
- Add bidirectional translation lookup so pt→en queries find en→pt entries
stored by English Wiktionary loader, with reverse index for performance
- Fix frequency loader: auto-detect column order (count\tword vs word\tcount),
auto-detect ISO-8859-1 encoding and convert to UTF-8, insert missing words
instead of only updating existing ones
- Switch WordNet download from 3.1 to 3.0 to match WOLF/OMW synset offsets
- Add OpenSubtitles-derived Portuguese frequency list (hermitdave/FrequencyWords)
- Increase affix expansion cap from 30→80 forms per word for Portuguese gerunds

New /difficulty endpoint returns word difficulty scores (0.0-1.0).
New /rhyme endpoint uses CMU phoneme tail matching to find rhyming words,
sorted by frequency. Adds cmu_tail column migration with batch population
at startup, and index for efficient reverse lookups.

New endpoints: /antonyms, /backing, /pronunciation, /etymology with difficulty
scoring on /random. Cross-language synset backing links French/Portuguese words
to English equivalents via WordNet 3.0 synset IDs (matching WOLF and OMW offsets).
New loaders: Hunspell affix expansion (fr, pt-PT), English programmatic inflector,
CMU Pronouncing Dictionary, SUBTLEX-US frequency, CETEMPúblico frequency,
Open Multilingual Wordnet (Portuguese), and SQL-based difficulty scoring.
Schema v2 adds tables: antonyms, synsets, word_synsets, pronunciations, etymology
with migration support for existing databases.
