Bug: Filename mismatch: workflow expects vmlinux.bin but gets firecracker

The build.sh script copies the built binary as firecracker to the builds directory, but the "Prepare release assets" step in the workflow attempts to copy vmlinux.bin from each build directory. This filename mismatch will cause the release preparation to fail when running on the main branch, as the expected file does not exist.

Bug: Build outputs firecracker but workflow expects vmlinux.bin

The build.sh script copies the built binary as firecracker into the builds directory, but the "Prepare release assets" step in the workflow attempts to copy vmlinux.bin which doesn't exist. This mismatch will cause the release process to fail on main branch when trying to create release assets because $dir/vmlinux.bin will not be found.

Bug: Release step references non-existent file vmlinux.bin

The "Prepare release assets" step tries to copy vmlinux.bin from each build directory, but build.sh now produces a file named firecracker instead. The build outputs ../builds/${version_name}/firecracker while the workflow expects $dir/vmlinux.bin. This mismatch will cause the release preparation to fail on the main branch when trying to copy files that don't exist.
