Long-running MCP tasks can rebuild their lost record from the conversation

MCP servers are outside programs that add tools to Claude Code, and some of their tools start tasks that keep running for a while. Claude Code checks on those tasks. It can now notice when its record of such a task is missing while the conversation still holds the tool call that started it. In that case it rebuilds the record from that call.

Before doing so it waits once for connectors (the links to those outside services) to come up. It also handles tasks that have given up or been stopped.
