feat: CLI SUBSCRIBE/MONITOR streaming mode

- New pubsub.ts: startSubscribe/stopSubscribe/startMonitor/stopMonitor
- IPC: redis:subscribe, redis:unsubscribe, redis:monitor, redis:monitorStop
- Streaming messages pushed via webContents.send
- Preload: onSubscribeMessage/onMonitorMessage callbacks
- CliView: detect SUBSCRIBE/PSUBSCRIBE/MONITOR, switch to streaming mode
- Stop button with pulsing indicator (green=subscribe, yellow=monitor)
- Real-time message display with timestamps
- Auto-cleanup on unmount
- i18n keys (zh-CN + en)
