rsnix v0.4.0: GUI input foundation — PS/2 mouse + scheduler message queues
Mouse (IRQ12, stream mode): ByteRing generalized for both PS/2 devices,
ISR routes data-port bytes by the controller's aux bit; mouse_init with
bounded-ACK handshake (boots without a mouse); packet decoder with
bit-3 resync, screen-relative deltas, buttons. Exposed as /dev/mouse,
the `mouse` stream command, and `make test-mouse`.
Message queues (ADR 0003's GUI-era primitive): every task gets a static
16-slot TaskMsg ring; send/recv/recv_blocking with direct wake + tick
scan safety net for the lost-wakeup race; `msgrecv`/`send` commands,
`mouse <id>` routes real IRQ12 events into a task's queue, jobs shows
q=. `make test-msg` + `make test-disk` regression pass.
