A request for Qwen3.8-Flash-Next failed six times with nothing but "Failed to load
model from file". The path was ...-00006-of-00006.gguf: the LAST shard of a 6-part
split GGUF. llama.cpp opens a split model at shard 00001 and finds the rest itself;
handed any other shard it just fails. And the set was incomplete anyway — only
shard 6 was on disk, the download having pulled a single shard rather than the set.

So a .gguf path is now resolved before the load: a shard filename maps to shard 1,
and the whole set is checked first. An incomplete set raises once, naming which
shards are present and which are missing, instead of six identical retries of a
message that says nothing.
