amd64 and arm64 from the TUNA, NJU and official mirrors, verified with the
pinned SHA256 checksums from the release's SHA256SUMS.

Each *_IMAGE_URL may now list several mirrors of the same file. When
aria2c is installed, the file is split across all mirrors with a single
connection to each; otherwise curl or wget tries the mirrors in order,
skipping mirrors that fail or return an empty response. A partial
download is only resumed with the same downloader and mirror list.
Fedora now defaults to the TUNA, BFSU and NJU mirrors. The Aliyun
mirror is not used because it rejects aria2c.

Instead of a hard-coded file name, find the ISO in install-iso/ by
matching *Win*11*x64*.iso (case-insensitive), picking the highest
version-sorted name when several match. The QCOW2 path is derived from
the detected ISO name, falling back to an existing *Win*11*x64*.qcow2
in base-qcow2/ when the ISO is absent.
