Review Summary

This PR updates the @types/node dev dependency from 22.20.0 to 24.13.2 (a major version bump), along with the transitive undici-types update from 6.21.0 to 7.18.2. The change was split out from Renovate PR #26 for easier review.

Analysis

Scope: Only package.json and package-lock.json are modified. No source code changes.

Risk assessment — Low:

• @types/node is a dev-only dependency used solely for TypeScript type checking. It does not affect the runtime bundle.
• The codebase's usage of Node.js APIs is minimal (process.exit(), stdio transport via MCP SDK) — all stable APIs unlikely to have breaking type changes.
• The tsconfig.json has "skipLibCheck": true, which further insulates against incidental type conflicts from upstream .d.ts files.
• The removal of libc entries in the lockfile for @biomejs/biome platform packages is a benign lockfile format difference (likely from the npm version used to regenerate it).

Findings

No issues found. The change is clean and appropriate.

Overall Assessment

✅ Looks good to merge — assuming CI (build + tests) passes as noted in the test plan. This is a low-risk dev dependency update with no source code impact.
