Scope the recovery error match to the previous run's active attempt.

rejectedHistory reads every error item on the previous run's root node. Each attempt writes its own failure item, and earlier attempts' items are kept. If a run has an earlier attempt that received invalid_encrypted_content, and its latest attempt then fails for another reason on the same native thread, this check still returns true. The session is then reset to a fresh native session with portable history, although the latest attempt did not reject the native history.

Match the error to previous.activeAttemptId, which is already resolved as previousAttempt. Use the attempt-owned provider turn or equivalent attempt identity on the error item. Confirm the item field in packages/provider-core/src/server/failure.ts before writing the filter.

Review comment at @apps/server/src/orchestration-v2/ProviderTurnStartService.ts at line 1302:
Update the error-item filter in rejectedHistory to match errors from the previous run’s active attempt, using the attempt-owned provider-turn or equivalent identity field confirmed in failure.ts; retain the existing previous.rootNodeId check and avoid including failures from earlier attempts.
