[codex] Upgrade Codex Desktop to 26.519.41501

[0xcaff]

Summary

• Upgrade hosted Codex Desktop from 26.513.20950 to 26.519.41501.
• Update the bundled codex CLI derivation from 0.131.0-alpha.9 to 0.133.0-alpha.1 with refreshed platform hashes.
• Regenerate the webview and Sentry patch files for the new upstream asset names/layout.

Notes

The latest local update was found at /Volumes/data-lake/data-lake-1/codex-desktop-updates/versions/3044-26.519.41501, with version.xml reporting build 3044, short version 26.519.41501, and publish date Fri, 22 May 2026 16:29:41 -0700.

During dev-server validation, the app loaded successfully. The terminal still showed existing local-dev warnings for DoubleCommand appshot hotkey registration and recommended-skills git lookup fallback, but the browser page loaded and reported no console errors.

Validation

• DEV=1 nix develop --command yarn run prepare:asar
• patch sequence temp-applied against scratch-new-version-unmodified/asar and reproduced the generated patched files without .orig backups
• nix develop --command yarn server
• opened http://localhost:8214/; main Codex UI rendered and browser console error log remained empty after waiting
• nix build --no-link .#default

Follow-up pushed in d13763e:

• Fixed the mobile first-open sidebar animation by initializing the app shell motion value with a numeric 1/0 derived from initialSidebarState.
• Root cause: the sidebar visibility state was correctly restored, but the motion value was initialized with a boolean, so the first open on mobile snapped to the final width instead of animating.
• Validation: clean patch-apply check, nix build --no-link .#default, and in-app browser mobile viewport sampling at 390x844 showing the sidebar width animate through 21 distinct values from ~20px to 240px.
