Makefile: PROFILE=release, CARGO_FLAGS=--release; make release target
kept as no-op (now default). boot.sh: PROFILE=release default;
--debug flag opt-in. mksystem.sh: PROFILE=release default.
test-disk/fault/gfx/mouse/msg: all use --release.
All scripts syntax-checked.

boot.sh: replace esp/ + DISK_IMG with single SYSTEM_IMG on ide.0
(hooks into mksystem.sh --force for auto-staging).
boot-image.sh: delegate to mksystem.sh --chain (build-image.sh deleted).
build-image-release.sh: delegate to mksystem.sh --chain --gpt.
qemu.sh: flexible launcher uses SYSTEM_IMG; --chain flag for
full-chain build.
test-disk.sh: drop ESP_DIR (mksystem.sh stages everything).
test-fault.sh: boot system.img on ide.0 + CRASHLOG stick on ide.1;
replace deleted mkdisk.sh with inline mkfs.fat.
test-gfx.sh: system.img on ide.0, stage via mksystem.sh.
test-mouse.sh: system.img on ide.0, stage via mksystem.sh.
test-msg.sh: system.img on ide.0, stage via mksystem.sh.
Makefile: remove stale build-image.sh/mkdisk.sh references from help;
image target delegates to mksystem.sh --chain.
All scripts syntax-checked (bash -n). build-image.sh and mkdisk.sh
no longer referenced anywhere.

The kernel used to inherit whatever GOP mode the firmware picked
(QEMU/OVMF gave 1280x800). Now every surface derives from a fixed
800x600 canvas:
- uefi: typed EfiGopQueryMode/SetMode/GetMode fn pointers in
GraphicsOutputProtocol (were raw *mut c_void, never called).
- gop::select_gop_mode: scan the mode list for an exact 800x600
(32-bit BGR/RGB only, the driver assumes 4 Bpp), SetMode it; fall
back to the smallest mode that fits the canvas, then to the
firmware's choice. SetMode may move both the mode info pointer and
the framebuffer base, so both are re-read after the switch. Boot
log: 'gop: mode 3 selected — 800x600 (was 1280x800)'.
- tests: relative assertions are resolution-agnostic; test-gfx and
test-mouse had a boot-log race (shell line prints before the cursor
task line) — now wait for the cursor line instead of grepping once.
All four suites pass at 800x600. 0 build warnings.

The first visible GUI surface: real rect primitives, a single
shadow→display push path, and an on-screen mouse cursor that can
never race the text surface.
gop:
- fill_rect + push_rect(x,y,w,h): every raster op rasterises into the
RAM shadow, then push_rect copies the rect to the display (write-only,
still never read) and composites the cursor on top. blit_glyph and
scroll shifts now route through it.
- cursor overlay: 12x16 pointer (const-fn built from column lists) drawn
white with a black offset outline; position in one AtomicU64 (x:high
32, y:low 32) — unpack masks the low word (a bare 'as usize' cast is
a no-op on 64-bit). The cursor never enters the shadow, so erasing is
just a shadow push of the old rect.
- cursor_redraw after scroll shifts and once at spawn (the vt diff never
re-blits idle cells).
cursor task (task 2, spawned at boot when a mouse is present):
- owns the PS/2 ring; polls every 10 ms, moves the cursor (clamped),
tracks buttons, and forwards every event to a task's queue when
'mouse <id>' armed it (the window-manager input path).
- /dev/mouse is now a position device (x/y/buttons snapshot); 'mouse'
watches the cursor live (prints on change); 'cursor' prints one-shot
state; 'gfx' draws a status-bar demo; 'gfx check' is an in-kernel
pixel self-test (shadow readback, display readback, cursor overlay
purity) — PASS/FAIL per stage.
Tests (headless QEMU + monitor injection):
- make test-gfx (new): all four compositor checks PASS.
- make test-mouse (rewritten): cursor tracks mouse_move deltas, buttons
ride along, /dev/mouse snapshot, live watch, real-event queue routing.
- make test-msg: task numbering shifted (cursor is task 2; msgrecv is
task 3) — updated, still PASS.
- make test-disk regression re-passes. 0 build warnings.
