REACT DEVTOOLS BRIDGE HARDENS AGAINST RECONNECTS AND CORRUPTION

React's DevTools layer just got bulletproof: hoxyq landed four interconnected patches that eliminate silent state corruption, validate invariants before mutation, and handle extension reconnects with message buffering and handshakes.

The DevTools Bridge now buffers messages during extension port reconnects and enforces a readiness handshake to flush the queue in order, solving the scenario where Chrome kills a port mid-session and the user navigates back to DevTools [1]. That's paired with explicit validation of Store operation invariants before any mutation happens, so missing nodes, invalid element types, and inconsistent parent-child relationships now emit and throw instead of silently corrupting state [2]. The Bridge and Wall boundaries themselves are hardened by replacing `any`-based types with typed `mixed` values and runtime validation, modeling event dictionaries as event-to-payload maps and eliminating runtime payload-arity handling [3]. The standalone Bridge now fully shuts down when its WebSocket closes with re-entrancy protection [4], and EventEmitter error handling is tightened to preserve the first thrown error instead of swallowing it [5]. Over on React Native, huntie removed the `commander` dependency from the main package by refactoring the bundle script wrapper [6], and dropped the unused `--version` arg from the standalone bundle script [7]. Translation auto-updates continue rolling out across both repos.
