Bring the SUB-OS Graphical Desktop Environment (SUB-WM compositor, SUB-WT widget toolkit, icon set, modal dialogs, terminal emulator and the desktop apps) onto main alongside main's userland /sbin/init and framebuffer console. Conflicts resolved: - kernel/main.c: boot into gui_start_desktop() by default (unless nogui/text/ emergency/single), then fall back through fbcon + /sbin/init + shell when the GUI session closes or a text console is requested. Splash raised by default unless a text console is asked for. Kept main's fbcon include and the weave_preempt_selftest path. - Makefile: kept main's userland init compilation rules and kernel/elf.c, kernel/exec.c in CORE_SRCS; retained the feature branch's gui/ sources. - README.md: kept main's Weave Scheduler section and adopted the feature branch's Boot Logo / Console Font / Framebuffer Console / GUI Desktop docs. Verified: full x86_64 build links cleanly (kernel.elf + SUB-OS.img). Co-Authored-By: Claude Opus 4.8 <[email protected]> Claude-Session: https://claude.ai/code/session_01Fh5z6V7nGPbHvqVG5p4CXX
