README AppImage download URL 404s — asset filename mismatch (x86_64 vs amd64)

[brbr1414]

Description

The AppImage download command in the README returns a 404.

README says:
wget https://github.com/cuongducle/codex-linux/releases/latest/download/codex-desktop-linux-x86_64.AppImage

But the actual release asset (checked via GitHub API for v26.608.12217-7) is named differently:

codex-desktop-26.608.12217-7-linux-amd64.AppImage

i.e. the README uses codex-desktop-linux-x86_64.AppImage while the real asset uses the codex-desktop-{version}-linux-amd64.AppImage naming pattern (version-prefixed, amd64 instead of x86_64).

Steps to reproduce

curl -fsSL -o test.AppImage https://github.com/cuongducle/codex-linux/releases/latest/download/codex-desktop-linux-x86_64.AppImage
-> HTTP 404

Expected

Either the README should be updated to use the correct filename pattern (codex-desktop-{version}-linux-amd64.AppImage), or the CI release step should also publish a stable, version-independent alias (e.g. codex-desktop-linux-x86_64.AppImage) so the documented "latest" URL keeps working across releases.
