scripts: migrate all QEMU/test scripts to single system image

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.

 #
 # scripts/test-msg.sh — automated scheduler message-queue round trip.
 #
-# Builds the kernel, boots QEMU headless, and verifies inter-task
-# messaging end to end:
-#   - `msgrecv` spawns a task that blocks on recv_blocking
-#   - `send <id> <type>` delivers every message type in order
-#   - `mouse <id>` routes *real* IRQ12 mouse events into the queue
-#     (the window-manager input path)
-#   - queue-full is a clean error (16-cap; tested against the shell's
-#     own never-consumed queue)
-#   - jobs shows q=0 after everything drains, task back to blocked
+# Tests all message types (user, timer, key, mouse), real-input routing,
+# and queue-full boundary.
 #
-# Usage:
-#   ./scripts/test-msg.sh
-#
-# Environment:
-#   OVMF   firmware (default: /usr/share/edk2/x64/OVMF.4m.fd)
-#   QEMU   qemu binary (default: qemu-system-x86_64)
+# Env: OVMF, QEMU, SYSTEM_IMG
