PR Summary

High Risk
High risk because it places non-workflow JSON under .github/workflows/, potentially breaking GitHub Actions behavior and obscuring CI/publishing configuration changes.

Overview
Commits a new file at .github/workflows/npm-publish-github-packages.yml, but the content is not a GitHub Actions workflow—it is JSON with an Ethereum wallet_address, a balances array (token metadata, amounts, USD pricing/value, liquidity flags), and pagination/timestamp fields.

This appears to repurpose a CI workflow filename/location for wallet balance data, which could confuse CI configuration/review and may break or mask intended publishing automation.
