A dispose-driven bare abort() yields the same empty/reason-less aborted turn as a transient provider abort, but with #isDisposed set and #abortInProgress unset. #isRetryableReasonlessAbort matched it and routed it through #handleRetryableError, which created #retryPromise and scheduled a continuation the disposed guard then skipped without resolving the promise — hanging the in-flight prompt() in #waitForPostPromptRecovery during shutdown.
Guard the predicate on !#isDisposed so lifecycle aborts settle the turn, and add a regression test. Addresses review feedback on #2689.
