+refactor(devtools): single source of truth for shared protocol types
+
+The VNode tree node, component detail entry, and render event shapes were declared
+three times: in the browser extension, in the devtools UI, and in the kit client
+bridge. They now live once in @qwik.dev/devtools/kit (protocol module) as
+DevtoolsVNodeTreeNode, DevtoolsComponentDetailEntry, and DevtoolsRenderEvent, and
+every consumer imports them from there.
