- New MulticamPanel: rows/cols angle grid with the current angle highlighted, click-to-switch, 1-9 switch-and-split and cmd-1-9 switch-only shortcuts (focused-panel routed), deferred switch queue during playback. - src/oakui/multicam.rs: clip->connected-sequence resolution, multicam state detection (selection then playhead fallbacks), per-angle frame requests rendered through the process backend into an LRU cache. - Timeline clip context menu Multi-Cam checkable item wired to oaktimeline::multicam enable/disable with undo. - Engine trait extended (real + mock); mock drives the real command path with synthesized angle frames.
