Note

Medium Risk
Medium risk because it changes public TypeScript types (e.g., FileResponse, queue/cluster params) and request body encoding behavior, which could affect downstream compilation and request formatting.

Overview
Bumps the SDK to 0.38.0 (manifest, package.json, src/version.ts) and refreshes generated resources from an updated OpenAPI spec.

Client/runtime fixes: stops removing the abort listener in fetchWithTimeout (avoids premature cleanup) and adds explicit support for application/x-www-form-urlencoded bodies by query-stringifying plain objects; tightens some JSON parsing typings.

API surface/type updates: removes FileObject and reshapes FileResponse (drops LineCount, makes fields required, and constrains object literals), strengthens several response object literal types across resources, expands/clarifies beta cluster and jig queue schemas (e.g., clusters.create.region becomes string, queue responses gain required typed fields/metrics), and updates numerous endpoint/docstring descriptions.

Dev/test/docs: updates CONTRIBUTING test instructions to use ./scripts/mock, adjusts tests for the new shapes/values, and skips tests that the mock server can’t support (octet-stream/callbacks).

Abort listeners accumulate across completed requests

Medium Severity

fetchWithTimeout no longer removes the abort listener from the caller-provided signal after fetch completes. Reusing one AbortSignal for many requests now retains one closure per request, causing unbounded listener growth and extra abort callbacks long after requests have finished.
