- oakengine_sequence_get_video_params (width/height/pixel aspect) with assertions for the default 1920x1080 square-pixel sequence and the invalid-handle path - oak-cli now renders at the sequence's real dimensions instead of the hardcoded 1920x1080
- oakengine_init/shutdown with HEADLESS/RENDER flags: headless boots Config, NodeFactory, ColorManager, task/conform/proxy/frame/disk managers and the serializer (plus an offscreen QGuiApplication that Qt requires for QAction); RENDER adds RenderManager. Idempotent and upgradable, no UI anywhere - oakengine_project_* (17): create/load/save, modified state, name, footage enumeration with online check, undo/redo, sequence access - oakengine_sequence_* (13): name, length (seconds and rational), frame rate, per-type track counts, playhead (timestamp and seconds), work area, markers; sequences are borrowed handles owned by their project - pure-C oakengine_init_test covers init idempotency, save/load round-trip through a real fixture project, footage online checks, timeline parameters, and NULL/bounds safety - no GL required
