- ViewerOutput owns timeline markers/work area via refcounted OakTimeline* value handles (oaktimeline_*_create) instead of C++ objects - oaktimeline C API: add marker_list_create/marker_add/ workarea_create/workarea_set_enabled; handle boxes gain an optional deleter for owning handles - oaknode_node_get_markers/get_work_area return addref'd OakTimeline* handles via out params (named-struct forward declarations avoid the public header cycle); drop OakNodeMarkerList/OakNodeWorkArea - serializers 210528-230220 load/save markers and work areas through the oaktimeline C API; SerializedMarker POD replaces std::vector<TimelineMarker*> in the serializer interface - Sequence::add_default_nodes uses oaktimeline_add_track_command - clip.cpp display-mode enums come from the new neutral include/timeline/displaymode.h; delete src/node/transition/timeline - oakcommon xml: add oakcommon_xml_reader/writer_wrap_native borrowed wrappers (C++ adapter use) - liboaknode now has zero C++ symbol references into liboaktimeline Tests: new owning-handle and wrap_native cases; all standalone trees green (common 196, codec 22, audio 40, task 110, render 49, timeline 123, node 96, plugin 100).
