/**
 * `pickRepoLabel` feeds the commit and change-request dialog titles, which
 * render it through `integrations:commitChangesScoped` / `createScoped`. Two of
 * its three branches used to return hardcoded English ("All repos",
 * "Repository") inside those now-translated titles; these cases pin that they
 * resolve through the catalog while the repo-name branches keep returning
 * user data verbatim.
 *
 * `vitest.setup.ts` initializes i18next in `en`, so `t()` returns the English
 * catalog values here.
