scripts: rebuild the dev loop around build.sh/run.sh

`make` did not parse at all (missing separator at line 139), so every
make target was dead.  The folder also carried three overlapping
launchers (boot.sh, qemu.sh, boot-image.sh) plus a fourth partial one
in the Makefile, `cargo build --package rsdos` copy-pasted eight times,
the QEMU invocation copy-pasted per script, and the test helpers
(fail/wait_log/wait_qemu_exit/qemu_hmp) duplicated in five tests.

New layout:
- scripts/lib.sh: single config (image, OVMF, mem/smp), the one cargo
  invocation (build_all), the one QEMU shape (qemu_args), and the test
  harness (test_boot, wait_log, wait_qemu_exit, qemu_hmp, sendkeys)
- scripts/build.sh: kernel + every bins/* in one pass
- scripts/mksystem.sh: freshness-aware image build that now stages
  every bins/*.efi into /bin/cli|gui (they were never copied before)
- scripts/run.sh: build + stage + boot in one command; --headless,
  --debug (GDB stub), --monitor (HMP socket), --fresh, --mem/--smp/
  --bios/--image; on Wayland it auto-selects XWayland plus
  grab-on-hover so the mouse can be captured (Ctrl+Alt+G toggles)
- scripts/tests/: the five automated tests on the shared harness
- deleted: boot.sh, qemu.sh, boot-image.sh, lib-boot-args.sh,
  build-image-release.sh, build-bootloader.sh (rsboot chain dropped)

The Makefile is now a thin wrapper: make run, make test, make system,
make inspect, make help.  Two-command flow: ./scripts/build.sh then
./scripts/run.sh (run.sh alone also works).

Stale test assumptions fixed so the suite is green again: test-gfx
waited for "gfx: check" while the shell prints "gfx check: PASS";
test-mouse/test-msg hardcoded msgrecv = task 3 (wm-input took slot 3 —
ids are parsed from the log now); the queue-full probe targeted task 0,
whose exec pump drains its own queue as completion codes (moved to the
cursor task, which never recvs).

Verified in QEMU: make test -> test-disk, test-gfx, test-mouse,
test-msg, test-fault all PASS.
