shared ToolCheck service, welcome status, logo doubled

ToolCheck kernel service checks ptyc/pql/tmux/git availability
once at boot, shared by status bar and welcome screen. Welcome
status line shows "application ok" in green or lists missing
tools in amber. Logo doubled to 144px. DialogHost moved inside
Expanded to fix blank workspace. Welcome maxWidth 850px, path
overflow fixed with Flexible.
