logitech-ipc-protocol: reconstructing Logi Options+ agent messages

logitech-ipc-protocol reconstructs the Logi Options+ agent's local IPC messages for querying devices and changing their active host. Its notes specify binary framing, JSON request paths and protobuf payload types across macOS sockets and Windows named pipes. The repository includes client scripts and records a Windows 2.7 change that routes access through the app's renderer relay.
