docs: Werkbaum-Plan nutzt die neuen Features selbst (D24: lebende Projektübersicht)

IDs (#scaffold, #docs, #resolve, #closure) und sechs echte
Abhängigkeiten — alles Serverseitige zeigt auf :#scaffold und
demonstriert damit die geteilte Closure; die Tracker-Wahl ist jetzt eine
=-Gruppe (genau einer), 'Update by itself' und das IntelliJ-Kapitel
starten per > eingeklappt, < holt die Zweiter-Parser-Warnung hervor;
eine "-Kurzbeschreibung am Collaboration-Knoten und zwei Langtexte
(#closure, #scaffold) hinter ---. Die in D40-D42 gebauten Knoten stehen
auf [x]. Parst mit 165 Knoten ohne Warnung, Pfad exakt, keine
Status-Diskrepanzen.

+#closure
+  The cheapest path pulls every dependency of a needed node into the
+  needed set, and shared targets count only once. That is why an
+  alternative can win although it looks more expensive locally: its
+  dependencies are already paid for elsewhere (see D34 and D42).
+
+#scaffold
+  Spring Initializr project with Gradle Kotlin DSL on JDK 21.
+  Everything server-side hangs off this one node — that is what the
+  :#scaffold dependencies across the tree point at.
