refactor: add shared types and improve ChatStatusBar with i18n

- Add electron/shared/types.ts as single source of truth for
  TokenUsage and AgentRuntimeStatus across main/preload/renderer
- Refactor ChatStatusBar.vue to use shared types and i18n keys
  instead of hardcoded phase text mappings
- Add phaseShort translations for zh-CN and en-US
