Kernel / memory: - mm/kmalloc.c: fix "Heap: Out of memory" under the GUI. The desktop allocates three full-screen 32-bit buffers (~11MB) which overflowed the fixed 16MB pool. The heap now starts at 32MB and grows on demand from the PMM (16MB regions), with region-safe coalescing (only merges physically adjacent blocks) so growth never corrupts across separate PMM allocations. Adds heap_get_grow_count(). Build / run: - Makefile: merge `run-gui` into `run` so `make run` boots into the graphical desktop; add `run-headless` (serial-only via QEMU_CMD), bump guest RAM to 256M, update .PHONY and help. Configure: - scripts/kconfig/menuconfig.py: gate the curses UI behind isatty() on stdin and stdout so non-interactive `make configure` stops emitting "nocbreak() returned ERR" and falls cleanly through to the non-interactive writer. GUI / userland: - gui/gui_apps.c: rebuild the System Monitor from hardcoded values into live telemetry -- real heap used/total/free with a colour-shifting bar, a scrolling heap-utilisation graph, the grow counter, and real PMM RAM figures. - lazybox `free`: report how many times the heap has grown. Auth: - Default login is now SUB / SUB (Kali-style username==password), seeded first as the primary uid-0 account and set as the logged-in user; root kept for compatibility. Hardcoded "root" defaults (whoami, su, passwd, ssh, sshd session) updated to SUB. Verified: clean build on x86_64/aarch64/armv8i; GUI boots with 0 OOM/0 panic; auth engine initialises cleanly; `make configure` fallback is clean.
