- Extract a shared normalizeToSupportedLocale helper in @fusion/i18n used by
both the CLI env detection and the dashboard navigator detection
(convertDetectedLanguage), fixing multi-subtag navigator tags (zh-Hans-CN)
and unifying Chinese script resolution.
- Add a cross-tab storage listener to useLanguage so a language change in one
tab propagates to others.
- Dedup the namespace lists into packages/i18n/namespaces.json, consumed by
config.ts and all three build scripts (no more 3-way drift risk).
- Add tests: dashboard i18n/index.ts (document.lang mirror, init non-blocking),
useLanguage concurrent-hydration race + cross-tab adoption,
normalizeToSupportedLocale, namespace-source consistency.

Create the @fusion/i18n package as the authored source-of-truth: shared
i18next config (namespace split, script-aware zh-CN/zh-TW fallback, plural
setup), en base catalogs, and a generated CLI static-import map so the
terminal surface is drop-in for new locales. Add the i18next-cli workflow
(extract/sync/types/status/lint) wired as root i18n:* scripts, install the
i18next stack into dashboard + CLI, strip @fusion/i18n from the published CLI
manifest, gitignore the generated dashboard catalog tree, and add a changeset.
