chore: release packages

[btravers]

This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

Releases

@temporal-contract/client@3.0.0

Major Changes

• 8d0750f: Replace neverthrow with unthrown for the Result/error-handling spine across all packages. This is a breaking change to the public API.

  What changed

  • ResultAsync<T, E> → AsyncResult<T, E>. Every activity, workflow-context, child-workflow, schedule, and typed-client method that returned a ResultAsync now returns an AsyncResult. The unthrown peer dependency replaces neverthrow.
  • No okAsync / errAsync. Lift a synchronous Result with .toAsync() instead: ok(value).toAsync(), err(failure).toAsync(). Promise boundaries use fromPromise(promise, qualify) / fromSafePromise(promise).
  • Narrow before accessing the payload. Both the result.isOk() / isErr() / isDefect() methods and the matching free functions isOk(result) / isErr(result) / isDefect(result) (imported from unthrown) are type guards; the codebase uses the methods. Narrow before touching .value / .error / .cause.
  • New defect channel. Unanticipated throws (a thrown exception the code did not model) now surface on unthrown's third defect channel — inspected via result.isDefect() / result.cause and re-thrown at the edge — rather than as a typed err. Deliberate boundary classification (e.g. mapping a Temporal SDK rejection to WorkflowExecutionNotFoundError) still produces a modeled err. result.match({ ok, err, defect }) folds all three.
  • WorkflowScopeError removed. Non-cancellation errors thrown inside cancellableScope / nonCancellableScope are unmodeled failures and now ride the defect channel. The scopes' error union narrows to WorkflowCancelledError.
  • The client's "unexpected" RuntimeClientError wrap is gone. An unanticipated rejection in a client operation now surfaces as a defect, not a manufactured RuntimeClientError. RuntimeClientError is still produced by deliberate boundary classification.
  • Error classes use TaggedError. The worker WorkerError hierarchy and the entire client TypedClientError hierarchy are now built with unthrown's TaggedError, each carrying a _tag discriminant (foldable with matchTags). The _tag is package-namespaced — e.g. "@temporal-contract/WorkflowExecutionNotFoundError" — so it never collides with a consumer's own tags; each error's .name stays the bare class name for readable logs. ChildWorkflowCancelledError is now a sibling of ChildWorkflowError (distinct _tag) rather than a subclass — discriminate on _tag / instanceof ChildWorkflowCancelledError instead of relying on instanceof ChildWorkflowError matching cancellation. The worker's ValidationError subclasses are unchanged — they still extend Temporal's ApplicationFailure for terminal-failure semantics.
