Migrates from the abandoned tokio-tar library to the actively maintained astral-tokio-tar to address CVE-2025-62518 (TARmageddon), a high-severity RCE vulnerability (CVSS 8.1). The vulnerability involves a boundary-parsing bug in PAX/ustar header handling that enables file smuggling attacks via malicious TAR archives. This is a drop-in replacement requiring only dependency updates in Cargo.toml files. The astral-tokio-tar library uses the same tokio_tar module name, so no source code changes are needed. All references to the vulnerable tokio-tar v0.3.1 have been removed from Cargo.lock and replaced with the patched astral-tokio-tar v0.5.6. Related to previous PR windmill-labs#6943 which was closed due to CLA issues. Security disclosure available at https://edera.dev/stories/tarmageddon and patch details at https://github.com/astral-sh/tokio-tar/releases/tag/v0.5.6
