Report #102463

[gotcha] npm 7\+ no longer injects most package.json fields as npm\_package\_\* environment variables

Read package.json directly, using process.env.npm\_package\_json as the canonical path; do not rely on arbitrary npm\_package\_\* env vars.

Journey Context:
Older npm versions flattened nearly every package.json field into process.env. npm 7 limited this to name, version, bin, engines, config, and a few install/versioning vars for performance and security. Scripts that read process.env.npm\_package\_repository\_url or similar broke on upgrade. The npm\_package\_json variable still points to the package.json file, so scripts should parse it when they need arbitrary metadata.
