Note

Medium Risk
Updates request/encoding behavior in the core client (abort handling and application/x-www-form-urlencoded bodies) and tightens/extends several public types (notably Jig volume versioning), which could affect runtime behavior and downstream TypeScript users.

Overview
Bumps the package to v0.38.0 (manifest, package.json, src/version.ts, changelog) and refreshes the generated spec metadata.

Client behavior changes: moves stringifyQuery into a new internal util (src/internal/utils/query.ts), adds application/x-www-form-urlencoded body encoding support using that helper, and fixes abort handling by no longer removing the abort listener too early.

API/schema updates: extends Jig deployment volume mounts with an optional version, adds volume versioning fields (current_version, version_history, mounted_by) to Jig volumes, loosens clusters region from a fixed union to string and updates region listing shape, and tightens various response object fields to string literals while removing the unused/broken FileResponse.LineCount and the exported FileObject type. Tests/docs are adjusted accordingly (skip mock-incompatible tests and update mock/pnpm instructions).

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.

Form encoding depends on exact content-type

Low Severity

buildBody() only switches to form-urlencoding when headers.values.get('content-type') equals exactly application/x-www-form-urlencoded. If callers set a valid variant like application/x-www-form-urlencoded; charset=utf-8, the body falls through to #encoder, likely producing a different encoding than the header implies.
