fix(ci): address PR review feedback for benchmark smoke tests

Security:
- Remove "Login to Hugging Face" step — it was a no-op (ephemeral
  --rm container) that exposed the HF token via CLI argument in
  docker inspect / /proc/*/cmdline. The eval step already
  re-authenticates via env var.

Functional:
- Remove feat/benchmark-ci from push trigger branches (won't exist
  post-merge).

Dockerfiles:
- Pin uv to 0.8.0 (was unpinned, fetching whatever latest ships).
- Add comment explaining the chmod +x ptxas workaround (Triton
  packaging bug — ships ptxas without execute bit).

Scripts:
- parse_eval_metrics.py: add note that it runs on bare host and must
  stay stdlib-only.
- parse_eval_metrics.py: add NaN guard for avg_sum_reward and eval_s
  (was only guarding pc_success).
