options to check whether options.timeoutMs is not undefined, so an explicit
value of 0 is forwarded to requestOptions.timeout. Add a regression test in the
Anthropic provider tests covering { timeoutMs: 0 }.

preserve OpenAI APIUserAbortError instances alongside native AbortError
instances, rethrowing either unchanged before handleOpenAIError. Extend the
openai test mock to expose APIUserAbortError, and add coverage in both
corresponding xai.spec.ts test paths for SDK cancellation propagation; apply

- createMessage: bridge metadata?.abortSignal into a per-request AbortController using the Bedrock pattern (pre-aborted guard + { once: true } listener) and pass the internal signal as the SDK request signal; existing client-level timeout mechanisms are untouched
- xai: rethrow AbortError unmodified from createMessage/completePrompt so callers can detect error.name === 'AbortError'
- tests: port reference completePrompt signal/timeout propagation tests and add per-provider createMessage bridging tests (pre-aborted signal rejects with AbortError; mid-flight external abort cancels the request)
…is PR only touches anthropic family)
- anthropic.ts: use options?.timeoutMs !== undefined (was truthy) so a caller-supplied timeoutMs: 0 is forwarded to the SDK instead of silently dropped; all 4 family providers now share the same defined-check - xai.ts: rethrow the OpenAI SDK's APIUserAbortError (exported from openai v5) unmodified from createMessage/completePrompt alongside native AbortError, since the SDK throws it when the request signal aborts and it would otherwise be mangled by handleOpenAIError - tests: anthropic.spec.ts regression test asserting timeoutMs: 0 reaches the SDK as timeout: 0; xai.spec.ts exposes the real APIUserAbortError in the openai mock and asserts the SDK abort error surfaces as the same instance (unwrapped) through both createMessage and completePrompt

- xai.ts: declare the streaming request body as OpenAI.Responses.ResponseCreateParamsStreaming instead of Record<string, any>, so the full request shape (incl. include/reasoning) is typechecked against the SDK and the as any on the create() call is no longer needed - xai.ts: type the stream as AsyncIterable<OpenAI.Responses.ResponseStreamEvent> (matching the codebase pattern in mimo.ts/openai.ts) and drop the as unknown as AsyncIterable<any> double cast, since the SDK create() streaming overload already returns an AsyncIterable stream - eslint-suppressions.json: reduce @typescript-eslint/no-explicit-any count for api/providers/xai.ts from 7 to 3 (four any usages removed)

Test listener cleanup after early generator closure.
Line 567 consumes the stream to completion. It does not test the finally path when a caller stops after the first chunk. Add a stream that yields one chunk and remains open, call stream.return(), and assert that removeEventListener receives the same callback reference.
As per coding guidelines, “Add focused tests” for relevant behavior; as per path instructions, “Check cleanup and deterministic async behavior.”

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Release external abort listeners after each stream.
{ once: true } removes the listener only when the task aborts. A successful stream or an SDK failure leaves the callback and its per-request controller attached to the external task signal. Repeated requests under one task accumulate retained listeners.
src/api/providers/anthropic.ts#L113-L113: retain the callback and remove it in afinallyblock that covers SDK creation and stream iteration.src/api/providers/minimax.ts#L100-L100: retain the callback and remove it in afinallyblock that covers SDK creation and stream iteration.src/api/providers/__tests__/anthropic.spec.ts#L480-L539: add a completed-stream test that asserts removal of the same callback.src/api/providers/__tests__/minimax.spec.ts#L438-L497: add a completed-stream test that asserts removal of the same callback.
As per path instructions, verify listeners and resources are disposed without stale state or duplicate work. As per coding guidelines, add focused regression coverage for the lifecycle behavior.

In `@src/api/providers/anthropic.ts` at line 113, Update the abort-listener
lifecycle in src/api/providers/anthropic.ts:113-113 and
src/api/providers/minimax.ts:100-100 by retaining the callback and removing that
same callback in a finally block covering SDK creation and stream iteration,
while preserving abort behavior. Add completed-stream regression tests in
src/api/providers/__tests__/anthropic.spec.ts:480-539 and
src/api/providers/__tests__/minimax.spec.ts:438-497 that assert the listener is
removed.

Wire the request-level
