Snider 754d6e2f93 fix(metal): error handling audit — propagate MLX errors instead of swallowing
Replace checkError() log+swallow with lastError() that returns real MLX
error messages. Add Eval/EvalAsync as error-returning variants of
Materialize. Generate loop now propagates GPU errors via model.Err().
LoadAllSafetensors returns (map, error). Model loaders check lastError()
after safetensors load. 180 tests passing.
