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.
