Refactoring Phase 3: AnimPreview + AnimSet aus EditorApp extrahiert

AnimPreviewController und AnimSetController in de.blight.editor.toolset.anim/
extrahiert (~1500 Zeilen raus). EditorApp: 13.187 → 11.650 Zeilen.
ToolContext um registry-Parameter erweitert, damit AnimSetController sich
nach Picker-Dialog selbst aktivieren kann.
