* Add a Polish interface
- pl.tsv: the full catalog (287 rows), written clean-room from the English
labels; plurals use the same one|few|many rule as Russian.
- Registered as the seventh language: "Polski" in the picker, locales pl,
pl-PL and pl_PL.UTF-8, complete_menus = true so the completeness tests
cover it.
- tests/polish.rs: the Polish UI test, modeled on the French one.
- README and AGENTS updated for the new language.
* i18n: add Czech (cs) interface language
Czech catalog with every key of the most complete catalog (287 rows), the
cs language entry with locale detection (cs-CZ, cs_CZ.UTF-8, ?lang=cs),
a Czech plural rule (1 / 2-4 / other) with a unit test, and the README
language list.

* i18n(pl): use Polish plural rule, so 21 is "21 aplikacji"
plural_east_slavic treats 21, 31 and 101 as "one", which is right for
Russian but not Polish, where only 1 itself takes the singular.
