Release v0.1.2

fix: resolve Ctrl+C exit issue and fix terminal output formatting

- Add a global async Ctrl+C listener in `main.rs` to ensure the process exits immediately even during reconnect loops or auth failures.
- Adjust spacing in `print_node_info` (`config.rs`) by removing the redundant blank line above "Valid until" and appending one below it.
