Replaces the `DOKKU_ARCHIVE_MAX_SIZE` and `DOKKU_ARCHIVE_MAX_FILES` environment variables with global git properties (`archive-max-size` and `archive-max-files`), configurable via `dokku git:set --global` and surfaced through `dokku git:report --global`. Defaults remain `1073741824` bytes and `10000` entries.
Archives passed to git:from-archive and certs:add were extracted without symlink or path validation, allowing a crafted archive to write arbitrary files anywhere writable by the dokku user via symlink traversal. Extraction now pre-scans entries for absolute paths, parent traversal, and unsafe symlinks, applies the GNU tar `--no-unsafe-links` flag when available, and validates symlinks after extraction.
