Diego Rodrigues de Sa e Souza 143c087d47 feat(i18n): locale-expansion tooling — add-locale orchestrator, aliases, translation-ratio gate; retire duplicate 'in' locale (#12496)
Locale aliases (uk, fil/tl, zh-hant, legacy in→id) with fixed browser/CLI/cookie detection; config/i18n.json shipped in the npm package; duplicate 'in' locale retired (42 honest locales); real-translation ratio gate with ratchet baseline (advisory); add-locale orchestrator + shared libs (batched translation backend, config-generated language bars, run-translation --adopt/--targets-only, scaffold helpers); tests derive the locale count from config with surface parity guards; docs and every public locale-count claim aligned.
