name the field when sampling content is missing (#689) Follow-up to [this thread](https://github.com/dart-lang/ai/pull/685#discussion_r4063946725) on #685. A `SamplingMessage` without `content` now throws an `ArgumentError` naming the field, instead of a `TypeError` from the cast. Its wording follows the other missing-field checks under `lib/src/api/`.
