chore(npm): enable engine-strict, disable audit

[caugner]

Description

Adds .npmrc enabling engine-strict and disabling audit.

Motivation

1. Enabling engine-strict prevents npm install with npm 10, which changes the package-lock.json.
2. Disabling audit suppresses the misleading audit message.

Note: With disabled audit, dependencies can still be audited via npm install --audit or npm audit.
