fix(quickget): extract Archcraft version folder from redirect URL

The hash URL was incorrectly using 'v${RELEASE}' (e.g., 'vlatest')
instead of extracting the actual version folder from the redirect URL.
Since releases_archcraft returns 'latest', the download redirect goes
to a versioned folder like 'v25.10', but the hash file lookup used
'vlatest' which doesn't exist.

Extract the version folder from the redirect URL to construct the
correct hash file path.
