- Add the wm window-manager facility per ADR 0004: overlapping
pixel-surface windows, damage-rectangle compositing, WM-drawn title
bar, focus/minimize/close, and F1-F4 keybindings
- Add gop shadow compositing primitives and vt::repaint_region so the
console stays layer 0 beneath windows
- Route mouse (absolute coords, press/release edges) and keyboard
(focus-aware input pump) to the focused window
- Add the rspaint drawing-program crate (pen, 8 colors, clear) and shell
draw/windows/restore commands
- Extend TaskMsg with AppMouse/Focus/Close and document the design in
CONTEXT.md + ADR 0004

- Add polled EHCI (USB2) and UHCI (USB1.1) host-controller drivers with
HID boot mouse support, wired into cursor polling and the 'usb' shell cmd
- Add USB Legacy ownership handoff (claim_usb_legacy) plus config_write_byte
- Harden boot: verify the PIT/timer ticks before shell entry, EOI stray
interrupts in the LAPIC to stop interrupt storms, bound PS/2 controller
waits, and INTx-disable AHCI (polled driver)
- Add boot stage markers, klog screen echo, and QR lock; scheduler
mark_shell_running; NO_USB stopgap to keep BIOS USB-Legacy input alive
- alloc_pages_above for DMA buffers that must avoid low conventional memory
- Expand DEBUG_NOTES with EHCI/QEMU bring-up findings

Polled xHCI driver (mouse-only): controller bring-up, port reset,
enable-slot -> address-device -> config-descriptor walk -> HID boot
mouse IN endpoint, one outstanding IN TRB drained on poll. Cursor
task polls usb first, PS/2 second. New 'usb'/'usb rescan' shell cmds.
Verified in QEMU (q35 + OVMF + qemu-xhci + usb-mouse): movement and
all three buttons tracked exactly; heap stays clean.
Fixes en route: MaxPorts=HCSPARAMS1[31:24]; operational regs CRCR=0x18
DCBAAP=0x30 CONFIG=0x38; pass input-context ptr in Address-Device;
Input Control Context DW0=Drop DW1=Add; HID walker bInterfaceClass at
+5; async discovery from cursor task.

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.
