Malicious code in @onereach/condition-builder (npm)

Analysis
@onereach/condition-builder@1.0.10 ships a preinstall hook (setup.mjs) that downloads the Bun runtime and executes a 727KB heavily-obfuscated script (math_init.js) at install time. The obfuscated script uses a custom string-encoding scheme that hides its behavior from static inspection and is unrelated to the package's declared purpose as a Vue.js UI component. Installing the package runs this opaque payload on the victim's machine.
