Note

Medium Risk
Adds a postinstall script that writes to /tmp, which will execute automatically during installs and can affect CI or developer environments. Otherwise changes are limited to package metadata/test script removal.

Overview
Updates package.json to minimal package metadata (name, version, empty dependencies) and removes the test script.

Adds a postinstall script that writes a CANARY_MARKER file to /tmp/postinstall-canary.txt to verify install-time script execution.

Test stub overwrites real package.json configuration

High Severity

This change replaces the project's functional package.json with a minimal test stub. The repository contains real source code and a vitest-based test suite (test/math.test.ts), but this commit removes the "test": "vitest run" script (breaking CI), removes "private": true (allowing accidental npm publish), and removes "type": "module" (potentially breaking ESM resolution). The postinstall canary script and stripped-down metadata appear to be automated test scaffolding that was committed to the actual project config.
