Resuming an interrupted turn: stale permission cards dropped, tool-call cleanup narrowed

What

When a session is resumed, Claude Code can pick up a turn that was cut off. A turn is one round of Claude working on your request. This release changes two parts of that:

• Restored permission card: a permission card is the prompt asking you to approve an action. One restored for an interrupted turn is now dropped once the last API error is older than an age limit. An API error is a failed request to Anthropic's servers. This case is recorded as resume_card_past_error_age_limit. Before, a stale API-error entry blocked the resume in every case, with no exception for a restored card.
• Unfinished tool-call cleanup: a tool call is Claude asking to run a tool, such as reading a file. The step that removes unresolved tool calls and shutdown-unwind tool results now finds turn boundaries and scans only the last turn. Before, shutdownUnwindResultsDoNotResolve handling scanned the whole transcript. It also gains an isRescueContinuation option.
• Shared settings: the rescue-continuation and opensNoTurn arguments are now passed through the helpers that trim the message history.

The gate tengu_partitioned_finch is read with a fallback of true. A gate is a switch Anthropic can flip from its servers. Nothing has been read about this gate yet.

Why

These changes decide which interrupted turns come back on resume and which tool calls are dropped from the history. If a resumed session behaves differently after a long-past API error, this is the likely reason.
