Add npm homepage metadata

[wowsofine]

Summary

• add the package homepage field pointing to the project README
• keep the existing repository and issue tracker metadata unchanged

Validation

• node package metadata smoke
• npm pack --dry-run --ignore-scripts
• npx --yes -p @yarnpkg/cli-dist@3.2.4 yarn build
• NODE_OPTIONS=--openssl-legacy-provider npx --yes -p @yarnpkg/cli-dist@3.2.4 yarn test
• git diff --check

Note: yarn install --immutable currently reports an existing lockfile drift around @types/node. A regular Yarn 3.2.4 install completed with warnings so build and tests could run locally.
