PR Summary

Low Risk
Dev-only lockfile changes with no application source edits; main impact is browser-sync/WebSocket dev server behavior and security patches in transitive ws.

Overview
Updates transitive dev dependencies in package-lock.json only: engine.io 6.5.3 → 6.6.9 and socket.io 4.7.2 → 4.8.3 (pulled in via browser-sync for local dev tooling, not direct app runtime code).

The lockfile refresh also bumps related packages—ws to ~8.21.x, cookie to 0.7.2, debug to 4.4.x, cors 2.8.6—and drops @types/cookie in favor of @types/ws on the engine.io dependency tree. Engine.io 6.6.9 specifically raises ws for CVE-2026-48779; socket.io 4.8.x includes fixes around io.close() on a stopped server and improved shutdown behavior.
