/**
* Ask the active UI provider and wait for the user's answer.
*
* Human-interaction requests are only valid from a top-level agent: a
* delegated subagent has no human answerer in its own context, so asking
* there would block forever. This mirrors the goal tools' top-level-only
* authority (`create_goal` rejects non-top-level agents).
* When a caller supplies an agent, human interaction is valid only for the
* exact live runtime root. Runtime ownership, not durable session lineage,
* decides this boundary: an owned child has no human answerer and would
* block forever, while a lineage-bearing session resumed as a new runtime
* root may ask normally.
*
* @param request Questions, owner agent, and abort signal.
* @returns The answer chosen or typed by the human.
* @throws {UserInteractionError} code `DELEGATED_CALLER` when the calling
* agent is a delegated subagent (`session.header.delegationDepth > 0`).
* @throws {UserInteractionError} code `CALLER_NOT_LIVE` when a supplied
* agent is not the registry's exact live instance, or `DELEGATED_CALLER`
* when that live agent is owned by another agent.
