Show reconnect guidance when disconnecting from tasks (#40629)

## Why

Exiting a TUI connected to a persistent app server can leave work running, so
the existing session-exit summary does not explain how to reconnect or stop the
active turn.

## What changed

- Distinguish disconnects, interrupted turns, and removed threads when building
  exit summaries.
- For daemon and remote sessions, report whether work may still be running and
  print commands to reconnect or stop the current turn.
- Sanitize remote WebSocket addresses in displayed commands and preserve the
  configured remote authentication environment-variable option.
- Keep the existing token-usage and resume summary for embedded sessions.

## Testing

Add coverage for daemon, remote, interrupted, embedded, archived, and deleted
session exits, including credential sanitization.
