[docs] client-api.md points to wrong test path (test/ → tests/e2e/) — MMLU-Pro example fails

[drunkcoding]

Summary

docs/client-api.md:254 documents the MMLU-Pro example with the wrong path. Running it verbatim fails with No such file or directory.

Verified on origin/main @ d171a15.

Detail

The doc says:

python test/r1_mmlu_pro_test/r1_mmlu_pro_batch_test.py \
  ...

But the file actually lives at:

tests/e2e/r1_mmlu_pro_test/r1_mmlu_pro_batch_test.py

(git ls-tree -r origin/main confirms there is no top-level test/r1_mmlu_pro_test/ — only tests/e2e/r1_mmlu_pro_test/.)

Fix

Update the path in docs/client-api.md to tests/e2e/r1_mmlu_pro_test/r1_mmlu_pro_batch_test.py. Recommend a quick grep for any other test/ vs tests/ path references in docs/ while touching this.

Provenance

Found during a full fresh re-verification of the v1.0.10.post4 release docs (client/format/deploy static cross-check). All other client-api.md class/method/parameter claims verified correct against batchgen/batchgen_client.py.
