/**
 * apes:* tab registration tests (Phase 1/1b, C6: 3 tabs). The fork registers
 * its three information-layer tabs (agents / apps / profile) through the same
 * BetterSidebarService the upstream builtins use (dogfood). `apes:tasks` was
 * removed in C6 — it overlaps the official DSH session tree in the native
 * sidebar. The spec pins the registration contract (id / single / order /
 * component presence) and the isolated i18n contract (the apes namespace
 * resolves zh vs en through the attached locale service, and every apesZh
 * key has an apesEn entry).
 *
 * Runs in the node vitest environment like builtins.spec.ts — no DOM, no
 * real DSH host (a live cordis scratch mount is Phase 2+).
