Clangd does not provide prebuilt binaries for {arch} to fetc

Error message

Clangd does not provide prebuilt binaries for {arch} to fetch from GitHub. Consider installing the binary manually.

What it means

ensure_arch_compatibility bails when running on linux with an architecture other than x86_64/x86, because clangd's GitHub releases only ship prebuilt x86 linux binaries; the user is told to install clangd manually.

Solutions

1. Install clangd via the system package manager (apt, dnf, pacman, brew) and point Zed at it
2. Use a supported architecture (x86_64 Linux) or a build of Zed for arm64 where clangd assets exist
3. Configure the clangd binary path manually in Zed settings to skip GitHub download
