0.2.3

What's Fixed

• Default server URL prefilled — new installs now show the official server address automatically, so mobile users no longer need to type the full URL.
• No more permanent connection dead-ends — a stale pending-connection journal (from a failed attempt with a different server URL, vault, or plugin version) is now discarded automatically and the connection restarts fresh instead of failing forever with a mismatch error.
• Honest connection feedback — a failed connect no longer incorrectly reports "连接成功" after the error notice.
