feat(apes): Phase 1 — 注册 3 个 apes:* 信息层 tab (tasks/agents/profile)

- 独立 src/client/apes/ 模块 (D1=B), index.tsx 仅 3 处最小改动
- 3 个静态占位 tab (react-icons FiList/FiCpu/FiUser), order 900+ 排在上游 builtins 之后
- 隔离 i18n 命名空间 'apes' (不碰上游 betterSidebar 字典), zh/en 双语
- index.tsx: attachApesLocale + 字典注册 + registerApesTabs effect
- tests/apes-tabs.spec.ts: 9 测试 (注册契约 + disposer + i18n zh/en/兜底)

gate: typecheck + build + test 1250 passed / 9 skipped / 0 failed

apps tab 延后 Phase 1b, messages 已砍 (无 DSH message-stream API)
