GUI: window/event exports, paint binary, event-loop gate

rsapi: WmEvent (kind=u8 enum: 0=key, 1=mouse, 2=focus, 3=close),
WmKeyKind (Char/Enter/Backspace/F1-F4/…), WmMouseEvent (x/y/buttons),
WindowInfo (ptr/w/h).  Five new exports: wm_create, wm_buffer,
wm_flush, wm_destroy, wm_recv (non-blocking TaskMsg dispatch → WmEvent).

Shell: abi_wm_* wrappers bridge rsapi types to rsnix::wm and
sched::recv(); wm_recv translates TaskMsg::Key/Mouse/Focus/Close
into flat WmEvent union.

bins/paint: gate binary — create_window + buffer + event loop with
Bresenham line drawing, color select (1-8), clear (c), F4 close.
All via wm_* ABI exports.

Fully migrated: date, mem, pci, cat, ls, mkdir, touch, rm, klog,
info, paint (11 external binaries in /bin/cli/ + 3 gate binaries).
