feat(gui): theme override, clipboard images, notifications, tray, layout helpers

Pass from codex implementing RFC spec gaps: theme_set IPC + state,
clipboard image read/write + MCP exposure, interactive notifications
and clearing, real tray tooltip/label/menu/message tasks, layout
heuristics (layout_suggest, layout_beside_editor, screen_find_space,
window_arrange_pair), dialog_message, focus_set, screen_work_area.
