chore: update package.json for dependency install smoke test

[pullfrog]

Updates package.json as part of a dependency installation behavior smoke test. The postinstall canary script confirmed that npm ci --ignore-scripts suppresses lifecycle scripts — /tmp/postinstall-canary.txt was never created.

Note

Medium Risk
Adds a postinstall lifecycle script that writes to /tmp, which can have side effects during installs in CI or developer machines if scripts aren’t disabled.

Overview
Updates package.json to rename the package, add a version, and replace the test script with a postinstall canary that writes CANARY_MARKER to /tmp/postinstall-canary.txt.

Removes private/type: module metadata and leaves an empty dependencies set, shifting the project toward a minimal install smoke-test setup.

Test postinstall script accidentally committed to repository

High Severity

The postinstall script (echo CANARY_MARKER > /tmp/postinstall-canary.txt) is a smoke-test artifact that the PR description confirms already served its purpose. It will now execute on every npm install (without --ignore-scripts), writing a canary file to /tmp. Meanwhile, the original "test": "vitest run" script was removed, breaking npm test for the existing test suite in test/math.test.ts.

Removed private field risks accidental npm publish

Medium Severity

The "private": true field was removed from package.json. This fixture repo (per README.md) was previously guarded against accidental publishing to the npm registry. Without it, an npm publish invocation would attempt to publish test-pkg@1.0.0 publicly.

Removed type: "module" may break ES module resolution

Medium Severity

The "type": "module" field was removed, reverting the package to CommonJS module resolution by default. The existing source files in src/ (.ts files) and tests importing them with ESM syntax (import { ... } from "...") may no longer resolve correctly depending on the toolchain configuration.
