Add 43 locales to the registry, their loaders and catalogs: Persian, Dari, Hebrew, Urdu, Pashto, Central Kurdish, Sindhi, Uyghur, Punjabi in both scripts, four regional Arabics, Hong Kong Chinese, Mexican and Argentine Spanish, European Portuguese, Canadian French, and 24 more. 34 wait for a native reader in review.json; ti, qu, gn, ay, bo and dv are not shipped. Every locale in Arabic or Hebrew script is rtl, and the registry test derives the script from the tag. rtl.css selects on :dir(rtl), so it holds inside a right-to-left region of a left-to-right page. resolve no longer leans on registry order: after the exact tag and the script, a request takes its own region, then the variant that serves it (CLDR parents for es-419 and pt-PT, Macau to zh-HK, the Arabic dialect areas), then the variant with no region, then the language's own region. pnb reaches pa-PK.
