Same root cause and fix as Guará: tauri-bundler's prepare_tools runs
'dd ... seek=8 conv=notrunc' on the cached linuxdeploy-x86_64 binary on
the aarch64 Gitea runner. A bash wrapper script there loses its shebang
to the dd and fails with ENOENT; a native ELF launcher survives because
bytes 8-10 of the ELF header are unused EI_PAD padding. Replace the
wrapper with a small ELF launcher compiled with cc, and cache
AppRun-x86_64 explicitly.
