model-downloader: tolerate huggingface_hub's bogus non-zero exit

After v0.0.186 added 'uvx --with click', the hf CLI starts downloading
correctly but raises 'typer.Exit(0)' that doesn't get caught — Python
exits non-zero despite the download succeeding ('✓ Downloaded' is in
the log, snapshot path written).

Wrap the uvx call with '|| true' and verify success by checking the
HuggingFace snapshot directory. Removes 'set -e' since we now handle
the uvx exit explicitly. Same fix for Qwen3.5-122B.yaml.
