Note

Medium Risk
Major dev-toolchain change: preset-env 8 peers on @babel/core 8 but core/cli/register are still 7.x, which can break npm run build or subtly change transpilation until aligned or verified in CI.

Overview
Bumps the dev dependency @babel/preset-env from 7.29.7 to 8.0.2 in package.json, with a matching package-lock.json refresh that pulls in the Babel 8 preset/plugin tree (8.x transform plugins, updated @babel/preset-modules 0.2.0, and newer polyfill helpers such as babel-plugin-polyfill-corejs3 1.0.0).

This is a major preset-env upgrade (Babel 8 line): preset-env now expects @babel/core ^8 as a peer, while the repo still pins @babel/core, @babel/cli, and @babel/register at 7.29.7. No changes to .babelrc.cjs (still a plain presets: ['@babel/preset-env'] with Node 20.16 targets and no useBuiltIns).

Reviewers should confirm npm run build (and CI binary builds that install global @babel/preset-env) still succeed and that compile output is unchanged.

ESM left untransformed for CJS build

High Severity

@babel/preset-env v8 changes modules: "auto" to assume ESM when the caller does not opt out. .babelrc.cjs relies on that default, while build rewrites the output package to "type": "commonjs" for pkg. Source import/export can remain ESM under a CJS package type, breaking dist binaries.
