v1.42.3 - Windows runtime refresh recovery

Windows usage refresh now recovers when a Codex update removes the executable discovered at Switch startup. Manual Refresh or the existing 60-second timer can use the replacement without restarting Switch. Available executable paths stay cached; rediscovery is serialized only when files disappear. An installation gap retains a visible warning and previous usage. Submitted requests are never replayed.

This maintenance release integrates community PR #107 with the current account-automation changes. It adds no dependency, background service, watcher or credential migration. macOS/Linux behavior is unchanged.

Download the complete package for your platform and keep its files together. Windows x64 and macOS15+ ARM64/Intel ZIPs include the runtime. Linux x64/ARM64 DEB/RPM/tar.gz packages remain integration previews; this release does not promote unsupported authenticated Linux desktop handoff.

Verification includes nine isolated runtime-recovery checks and actual hosted Windows same-window Refresh/timer tests against an unchanged 1.42.2 baseline, fictional accounts and offline RPC fixtures. All six protected native checks and ancestry-preserving author-reviewed merge precede publication. VERIFICATION.json, SHA256SUMS.txt and the verification ZIP bind the exact source, merged tree, runtime10.0.13, CI, package and image hashes. A live Microsoft Store update or authenticated account/chat continuation is not claimed.

Windows/Linux are unsigned. macOS bundles are native ad-hoc signed without Apple notarization. No owner installation, active Codex session or real account is changed by this public delivery. Previous releases remain available.

Known existing Linux preview UI detail: at minimum width, the English account-auto-switch caption can be clipped. The same native frame in1.42.2 reproduces it; it remains a separate follow-up, not a Windows recovery regression. Original Linux frames are retained in the verification archive.
