Remote sessions now recover subagent transcripts that were dropped

A subagent is a helper agent Claude starts to handle part of a task, and its transcript is the record of what it did. In remote sessions, which run on a server instead of your computer, Claude Code fetches these transcripts only when needed. It now keeps track of transcripts that were dropped from its local store and fetches them again. It also records two new outcomes: when its copy is behind, and when rows were lost.
