Incomplete Babel 8 major upgrade

High Severity

Bumping only @babel/core to v8 leaves Expo SDK 58's babel-preset-expo and the client's @babel/cli, presets, and plugins on Babel 7. Mixing majors is unsupported, so Metro transforms and any Babel CLI usage can fail to load or compile.

Approved: Dependabot dependency update with CI green (test, Metro, React 18/19, and Vercel checks passed). No approval-policy files apply, and this automation has no prior approval to re-evaluate.

_{Sent by Cursor Approval Agent: SDK approver}

cursor

Left a non-blocking comment. This major @babel/core 7 → 8 bump still keeps Babel 7 CLI/presets/plugins, and Bugbot flagged that mixed-major setup as high severity, so it is not an automatic approve. Human review is needed and no reviewers were assigned.

Babel 8 mixed with v7 plugins

Medium Severity

@babel/core is now 8 while @babel/cli, @babel/preset-env, @babel/preset-typescript, and the remaining plugins stay on 7 and peer-depend on @babel/core ^7.0.0-0. Babel does not support mixing majors, so any path that still loads babel.config.js (including loose and @babel/proposal-*) can fail or emit incorrect output.
