Three build-correctness fixes plus README coverage of the new kernel core. The Makefile had no header dependency tracking, so editing a header left every unrebuilt caller linked against the old layout. That is how the desktop's window paint callbacks silently landed at the wrong struct offset after gui_window_t grew: gui_apps.o was never recompiled. Compiles now emit .d files via -MMD -MP and the build pulls them in. The include has to sit at the end of the file with .DEFAULT_GOAL pinned to `all` -- a .d file's first rule would otherwise become make's default goal and turn a bare `make` into a silent no-op. drivers/video/canvas.c carried the same font table defect gui_gfx.c did: the `// \` comment on the backslash glyph continues onto the next line, swallowing the `]` entry and shifting every glyph from ']' onward by one, so all lowercase text rendered one letter off.
