Split translations into per-language files, lazy-loaded

Only English is bundled in index.html now; the other 19 languages are
emitted as dist/locales/<code>.json and fetched on demand when a visitor
actually uses one (via auto-detect, the picker, or ?lang=xx). This drops
index.html from ~511KB to ~318KB; a non-English visitor fetches just
their one ~8-10KB locale, which the service worker then caches for
offline use. t() falls back to English until a locale resolves.

- i18n.js keeps only en + a loadLocale() fetcher; locale data moved to
  src/locales/*.json.
- build.js emits dist/locales/; dev.js serves /locales/<code>.json.
- Deploy hook publishes the locales/ subdir.
