• Added selector choice persistence across program restarts. Choices are saved to sing-box-drover.state.json. Use selector-persist to enable or disable this behavior.
• Added auto mode for selector menu layout: nested submenus when there are many items, flat list otherwise.
• Selector menu items are now temporarily locked while the update is being applied.
• When the sing-box core fails, its output is now captured and shown in the error message.
• Connection flush failures during selector updates are no longer treated as errors.
• Added the sing-box version to the User-Agent header for BPF profile update requests.
