ChildResumeRunner typedef

ChildResumeRunner = Future<void> Function(String id, String message)

Callback to resume a child IN ITS OWN SESSION with a follow-up message (issue #222): the run appends to the same JSONL transcript, keeping the same mailbox id and display name. Backs task_resume (failed children) and task_send (idle/completed children). Null on hosts that cannot reopen child sessions — the tool descriptors then advertise the missing child-resume capability up front.

Implementation

typedef ChildResumeRunner = Future<void> Function(String id, String message);
