Cloud sessions can fetch subagent details in batches and keep fewer status rows

When Claude Code runs as a cloud session, it can now ask the server for details about several subagents at once, in batches. A subagent is a helper agent Claude starts to handle part of a task. The request is skipped when Claude Code is limited to essential network traffic, or when data is kept in a region outside Anthropic's own. Some server refusals are treated as permanent and not retried.

A "requesting" status row that comes right after a tool result, with nothing new added, is now sent as live-only. It shows up while the session runs but is not saved, when the server's settings allow it.
