openlogi-cli 0.1.2

//! `openlogi diag` — real-device smoke tests for the HID++ write path.
//!
//! Each subcommand exercises one round-trip (read → modify → read back →
//! restore). The intent is verification, not configuration: nothing here
//! touches `config.toml` or talks to the GUI; everything runs through the
//! same `openlogi_hid` API the GPUI app uses, so a green diag means the
//! GUI's write path works on this host.
