fix: replace SDK AbortSignal.timeout with application-level AbortController - #58

…ntroller The SDK creates an AbortSignal.timeout inside _createRequest, where the signal's only strong reference is the Request object's internal slot. Under memory pressure (observed on a GH Actions runner: 1004s against a 600s timeout, Node v24.19.0, undici 7.29.0), the signal may be garbage collected before it fires — a confirmed Node.js bug (nodejs/node#55428). Replace the SDK's timeoutMs option with an application-level AbortController + setTimeout in attemptOnce and lookupGenerationCost. The controller lives in function scope (immune to GC), the signal is passed via the SDK's fetchOptions spread path (skips the SDK's own AbortSignal.timeout), and clearTimeout on completion prevents leaked timers.

Rename "passes an AbortSignal that aborts after the configured timeout" to match what the test actually proves (signal exists and is not pre-aborted). Fix "does not sleep after the final attempt" to use non-zero retryDelayMs and spy on setTimeout — the previous version used retryDelayMs: 0, making the attemptNumber guard untested.

The comment claimed excluded paths "would fail or be skipped here for the same structural reason" — wrong. These are files successfully read in full by higher-priority channels (changed files, related files); they would succeed in the priority-doc channel too, creating duplication. The exclusion prevents that duplication, not a redundant failure. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add a regression test that exercises the actual timeout abort path: the stub's promise stays pending until the signal aborts, fake timers advance past both attempts, and the test asserts signal.aborted is true and the result is a retryable api_error. Without the AbortController wiring, this test fails. Wrap the clearTimeout spy in try/finally so mockRestore runs even if the test assertion or requestReview rejects.

The second attempt's abort rejection fired asynchronously before the .rejects.toThrow() assertion could catch it, producing an unhandled rejection error in CI (--unhandled-rejections=throw). Attach .catch() on the promise before advancing timers so both attempts' abort rejections are handled immediately. Also wrap the setTimeout spy in the retry-delay test in try/finally for consistent cleanup on assertion failure. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Drop generation responses from the clearTimeout test stub (delete sdk.generations so only the chat attempt's timer exists) — the test previously passed even if attemptOnce's clearTimeout was removed because lookupGenerationCost has its own timer. Replace the `as Error` type assertion in the abort test with `void promise.catch()` + `rejects.toThrow` — cleaner and follows the no-type-assertions convention.
