概要
working状态更新的问题。a2a-sdk的非阻塞SendMessage语义,补上returnImmediately=true时的初始Task(working)快照。变更说明
message:stream首个事件改为Task(state=working),不再使用通用TaskStatusUpdateEvent(state=working)作为初始快照。urn:opencode-a2a:extension:shared:stream-hints:v1时才发带metadata.shared.progress的TaskStatusUpdateEvent(state=working)。message:send阻塞模式保持不变;configuration.returnImmediately=true时先返回Task(state=working),后续由后台继续完成并持久化。docs/guide.md。验证
