[eric] diag: add targeted logs for each top crash-suspect (boot env snapshot for React-prod-mode + tree-shaking checks, wrapped lazy() loader with requested/loaded/failed logs for chunk-split race, [diag][ErrorBoundary] prefix on componentDidCatch so in-tree throws surface in stderr alongside window.onerror); retag v1.1.44
