DeepEP now records an HTTPS DeepJIT URL, so build_vendor no longer needs the git@github.com rewrite.

The trace file name starts with --model_name. The default is an HF id
(deepseek-ai/...), so the path gets an extra directory that is never
created and the export fails with FileNotFoundError after the run.
An absolute checkpoint path replaces --tracing_path altogether.
Use only the last path component of the model name.
