feat: CLI MULTI/EXEC transaction support

- CliView: detect MULTI/EXEC/DISCARD commands
- MULTI enters transaction mode (tx> prompt, yellow)
- Commands in tx mode are queued (QUEUED + queue count)
- EXEC executes all queued commands, shows array results
- DISCARD cancels transaction
- WATCH/UNWATCH handled as non-queued tx commands
- i18n keys for tx messages (zh-CN + en)
