build: split the engine into liboakengine.so; worker drops the UI entirely

Physical split: app/{audio,cli,codec,common,config,node,pluginSupport, render,task,timeline,undo,tool,shaders} plus coreengine, version and ui/icons+colorcoding move to a new top-level engine/ tree, built as liboakengine.so (shared). The render backends (oakgl/oakvulkan) move with it and link the engine library instead of embedding a static render-core subset (libolive-rendercore is gone). - oak-render-worker now links liboakengine instead of the whole libolive-editor object set: 336MB -> 2.9MB, no Qt Widgets UI - the editor links liboakengine for the engine and keeps only UI objects in libolive-editor - install/packaging: GNUInstallDirs libdir on Linux, bundle copy on macOS, oakengine.dll staged for NSIS, AppImage validation entry - fix backend lookup for the new layout: DynamicRenderer searched ../app but backends now live in engine/; a stale pre-split liboakgl in the build tree got dlopened instead, re-initialized and later destroyed the interposed engine statics (full-suite segfault at DialogSequenceParameterTab, found via gdb watchpoint)
