v0.2.3: Run without console window on Windows

- Add windows_subsystem = "windows" to prevent console window on double-click
- Use AttachConsole(ATTACH_PARENT_PROCESS) so CLI subcommands still work from a terminal
- Show MessageBoxW error dialog if daemon fails to start
- Remove hide_console() (now unnecessary)
- Fix unused import warning in ipc.rs (warn → tracing::warn! inline)
