npm / yarn / pnpm supply-chain audit

Read-only audit of the workspace root. Do not modify any files.

0. Detect package manager

test -f package.json || { echo "STOP: no package.json at workspace root"; exit 1; }
jq -r '.packageManager // "unset"' package.json
ls -1 yarn.lock package-lock.json pnpm-lock.yaml 2>/dev/null || true

If no package.json, stop. Priority: packageManager → lockfile → default npm.

1. Tool version
