feat: matrix room, room_info, research execute, bootstrap improvements

- bootstrap: create integration test room in Tuwunel, send bootstrap
  message, print room ID in summary
- room_info: list_rooms and get_room_members against live Tuwunel
- research: execute with empty tasks against real Matrix room + Mistral
- identity: fix flaky list_users_tool test (use search instead of
  unbounded list to avoid pagination)
