chore: update package.json for canary test

[pullfrog]

Updates package.json as part of dependency installation canary test. The postinstall script writes a marker file to /tmp/postinstall-canary.txt to verify whether scripts are executed during npm install.

Note

Medium Risk
Adds a postinstall script that executes during dependency installation and writes to /tmp, which can affect install environments/CI and may be undesirable in real packages.

Overview
Updates package.json to convert the project into a versioned package (name/version) and removes the prior test setup.

Adds a postinstall canary that writes CANARY_MARKER to /tmp/postinstall-canary.txt to detect whether install scripts run, and leaves dependencies empty.

Removal of test script breaks existing test suite

Medium Severity

The "test": "vitest run" script was removed even though test/math.test.ts still exists and imports from vitest. Running npm test will now fail. The stated intent was to add a postinstall canary script, but the entire scripts block was replaced instead of augmented, which inadvertently drops the test script, the "private": true flag, and the "type": "module" declaration.

Removing private flag enables accidental publishing with postinstall

High Severity

The "private": true field was removed at the same time a postinstall script performing filesystem writes (echo CANARY_MARKER > /tmp/postinstall-canary.txt) was added. Without the private guard, this package can be accidentally published to npm, causing the postinstall script to execute on every consumer's machine during npm install. This is a well-known supply chain attack pattern.
