docs(agentic-ci): document client_concurrency_mode in create_resource_provider

[github-actions]

What

Add the missing Args: entry for the keyword-only client_concurrency_mode
parameter in create_resource_provider
(packages/data-designer-engine/src/data_designer/engine/resources/resource_provider.py).

The parameter has existed in the signature
(client_concurrency_mode: ClientConcurrencyMode | None = None) without a
corresponding entry in the Google-style Args: block, causing docstring vs
signature drift.

Why

Detected by the docs-and-references agentic-CI audit as a signature-driven
docstring-drift finding. The fix is mechanical: the added entry notes the
parameter type and its documented default (ClientConcurrencyMode.ASYNC),
which is set explicitly a few lines below in the function body — no invented
semantics.

Testing

make test-engine — 2257 passed.

Greptile Summary

Adds the missing client_concurrency_mode entry to the create_resource_provider docstring.

• Documents that omitted values default to ClientConcurrencyMode.ASYNC.
• Makes no runtime behavior changes.

Confidence Score: 5/5

The PR appears safe to merge because the documentation-only change accurately describes existing behavior.

The new docstring entry matches the implementation, which resolves an omitted concurrency mode to ClientConcurrencyMode.ASYNC, and no runtime code is changed.

Important Files Changed
