Analysis

The postinstall hook (scripts/postinstall.js) beacons host platform data via HTTP POST to 193[.]70[.]34[.]101:20099/vote. On Windows and WSL it XOR-decodes a hardcoded URL, downloads a second-stage binary to the temp directory as main.exe, and launches it as a detached background process; on WSL it executes a bridge command via the shell. The package is a combosquat of the commander CLI with no functional content.
