New tests for what the port added: status tint priority and
context-dependent chip filters on the dewar/queue model, the
right-button wheel guard (motor protection), PopoutWindow edge maths,
manual-resize fallback, close-hides behavior and DockTitleBar, the
chip drag-drop relabeling, and the console-log pop-out mirror. The
widgets' __main__ self-checks are superseded by these and removed.
Brings PR diff coverage from 70% to 81% (gate: 80%).
