fix ClidePane notifying focus listeners during build

ClidePane.didChangeDependencies/didUpdateWidget run in the build phase and
called FocusTracker.setStatusWidget -> notifyListeners() synchronously,
rebuilding the focus-listening status-bar item mid-build — Flutter threw
"markNeedsBuild called during build" on every frame once a Claude pane was
focused. The convey now defers to a post-frame callback when mid-build
(re-checking focus then) and applies immediately otherwise. The T-150
widget tests missed this because no focus listener was in their tree;
added a regression test with PaneContextStatusItem present.

T-159.
