/**
 * Resolve prompt context for synthetic OpenCode user messages.

 * OpenCode records even ignored/noReply prompt messages as user messages. If a
 * plugin sends one without the previous model/variant, OpenCode's next prompt
 * can inherit the synthetic message's default model/variant and change usage or
 * cache attribution. Resolve the most recent assistant context and message IDs
 * so hidden replies preserve model state and active-run notifications can be
 * ordered before the assistant without becoming pending user work.
