Install NPM Dependencies with Caching

Works out of the box for most projects; the README states it covers 95% of use cases with a basic example, eliminating manual cache configuration.

Caches dependencies based on lock file hashes (e.g., package-lock.json or yarn.lock), ensuring efficient cache hits only when dependencies are unchanged, as detailed in the caching strategy.

Supports installing dependencies in multiple subdirectories with the working-directory parameter, demonstrated in examples for monorepos with separate package.json files.

Allows overriding the default install command with custom scripts, such as 'yarn --frozen-lockfile --silent', enabling tailored workflows without losing cache benefits.
