qemu and build: review fixes across the rig driver, boot script, and fetch helpers

Bounded waits and validated arguments in run.sh and ui-drive.sh, a seeded
settings directory and root-only staged rootfs permissions with their own
tests, qmp.py and imgtools.py hardening, the fetch scripts checking what they
download, and ASCII typography throughout. Each fix carries its test under
qemu/tests or tests/.

| `qemu-tools` | ubuntu-latest | shellcheck on `qemu/**.sh`, `tests/mk-bootimg/*.sh`, `tests/fetch-vendor/*.sh`, `tests/fetch-buildroot-tarball/*.sh`; runs the offline regression tests for the mk-bootimg probe, boot.img validation, run.sh argv ordering, mkimage's SEED_DIR hook, staged rootfs permissions, fetch-vendor, fetch-buildroot-tarball, and its own CI wiring; builds the initramfs (pinned busybox) and the A/B disk image. |

Uploads `quality.json`; fails if the security grade is worse than C. |
