Add the full Arabic Wiktionary, and answer in Urdu before English

Classical Persian quotes Arabic outright — Hafez opens with a whole hemistich
of it — and none of it resolved before. The full Arabic export brings 36,627
entries and 819,608 new form pairs, and the forms are the point: السّاقی,
الناس, تَلْقَ and تَهْوی are all conjugated or carry the article, so they only
reach a definition through that index. Nine of the ten Arabic words in the
sample now answer where none did.

The cost is real and worth stating: the database goes from 28 MB to 87 MB and
the release APK from 10.6 MB to 29.2 MB, with another 87 MB unpacked on first
run, so about 116 MB installed.

Results are now ordered the way a reader of this app wants them: the Urdu
definition first, because it needs no translating, then Persian, then sources
keyed on another language, with English arriving only through whatever is left.
Arabic sorts last outright — its index is larger than every other source
combined, which makes it the likeliest to match by coincidence.

No Persian-to-Urdu dictionary. Wiktionary's Persian entries carry no
translations at all; the tables live only on English pages, in a 3.3 GB export,
so it would mean pivoting through an English sense. A sample of that file
projects about 6,900 Persian words with any Urdu equivalent, mostly modern
dictionary vocabulary rather than the language of the poems — not worth the
pivot. tools/README.md records why, so the question doesn't get reopened from
scratch.

Verified on an API 36 emulator: عشق returns all five sources with the Urdu
definition at the top.
