v0.2.6

What's Changed

• Test-session cleanup (dev up): a start that fails half way now undoes itself (far monitor, nested compositor, view window); the time-limit watcher ends with its session instead of living on after dev down and ending a later session at the old deadline; nested_stop never sends the compositor exit without the session's signature (with none it addressed your own compositor).
