/**
 * A tool call's arguments, read the way models actually send them.
 *
 * The schema says an object, and most calls are one. But a model that has just been shown a list
 * will sometimes wrap it: `[{"question": "..."}]` instead of `{"question": "..."}`. Reported from a
 * real run — an ask_user call that spent eighteen minutes getting nowhere and came back with
 * `ask_user needs a "question" string`, when the question was right there, one bracket out.
 *
 * Rejecting it is defensible and useless. The intent of a single-element array holding one object
 * is not ambiguous, and the alternative is a wasted round trip that teaches the model nothing —
 * it re-sends the same shape, because from where it sits the shape looked fine. So a lone wrapped
 * object is unwrapped, and anything genuinely unreadable still comes back empty for the caller to
 * complain about properly.
 *
 * Deliberately narrow: only a one-element array, and only when that element is a plain object. An
 * array of two things is not a mis-wrapped argument, it is a different mistake, and guessing which
 * element was meant would be inventing an answer.
