@spec sample_async(
  map(),
  keyword()
) :: {:ok, map()} | {:error, Tinkex.Error.t()}

Async sample request.

Uses :sampling pool (high concurrency). Sets max_retries: 0 - Phase 4's SamplingClient will implement client-side rate limiting and retry logic via RateLimiter. The HTTP layer doesn't retry so that the higher-level client can make intelligent retry decisions based on rate limit state.

Note: Named sample_async for consistency with Elixir naming conventions (adjective_noun or verb_object patterns). The API endpoint remains /api/v1/asample.

Examples

Tinkex.API.Sampling.sample_async(
  %{session_id: "...", prompts: [...]},
  config: config
)
