How ShadowCanopy checks npm packages

ShadowCanopy blocks every dependency by default and only lets through what it can verify — against live malicious-package advisories, an AI behavior scan, and a byte-for-byte hash check. It protects installs across npm, PyPI, crates.io, pkg.go.dev, RubyGems, Maven Central, NuGet, Packagist, Hex, pub.dev, Swift Package Manager.
