Runtime now validates stackSize before constructing the Squirrel VM (previously the check ran after member initialization). DevTools singletons (AiPanel/ConsolePanel/McpServer/RenderVision) keep their process-immortal lifetime - required by the detached stdio reader thread and cross-singleton calls - but move from scattered raw new leaks to a single documented Immortal holder.
