Create versioned release tarball

The release workflow now produces a tarball named
`rayhunter-v<version>.tar`, where the version is dynamically extracted
from `rayhunter/bin/Cargo.toml`. Additionally, the archive contains a
top-level directory named `rayhunter-v<version>/`, making each release
artifact clearly identifiable and self-contained by version. This change
improves clarity for downstream consumers and simplifies managing
multiple versions.
