Add simuUiTreeRequest/Ready/Data/Size exports that serialise the live LVGL widget tree (screen, top and sys layers) to JSON so a host can inspect and drive the colour UI in automated tests. The snapshot is built on the GUI task from a hook at the end of LvglWrapper::run(), double-buffered and requested asynchronously; flags select skipping hidden subtrees and including per-node style data. Black-and-white builds keep the exports but report that no tree is available. Each node carries its LVGL class name, id (object address), absolute coordinates, visibility (display bounds plus ancestor clipping), state and flag booleans (emitted only when set) and widget-specific fields: label/textarea/checkbox text, textarea cursor, keyboard textarea and mode, btnmatrix buttons and selection, bar/arc value range, table cells and selected cell, image source and active tile. The root carries the LVGL version, tick, focused object and edit state. Add simuIsBootComplete(), latched from the GUI hook once edgeTxInit has run and the Lua interpreter is running, so hosts can wait for a responsive UI instead of sleeping. Bind both in the web host runner.
