feat(testing): rewrite test infrastructure from libvirt to direct QEMU

Replace the never-fully-operational libvirt-based VM test infrastructure
with direct QEMU management and archangel ISO for fully automated,
unattended base VM creation.

Key changes:
- vm-utils.sh: complete rewrite — QEMU process mgmt via PID file,
  monitor socket for graceful shutdown, qemu-img snapshots, SSH
  port forwarding (localhost:2222)
- create-base-vm.sh: boots archangel ISO, SSHs in, runs unattended
  install via config file, verifies, creates clean-install snapshot
- run-test.sh: snapshot revert, git bundle transfer, detached archsetup
  execution with setsid, polling, validation, and report generation
- debug-vm.sh: CoW overlay disk, GTK display, auto-cleanup on close
- setup-testing-env.sh: reduced deps to qemu-full/sshpass/edk2-ovmf/socat
- cleanup-tests.sh: PID-based process management, orphan detection
- validation.sh: port-based SSH (backward compatible), fuzzel/foot for
  Hyprland, corrected package list paths
- network-diagnostics.sh: getent/curl instead of nslookup/ping (SLIRP)

New files:
- archsetup-test.conf: archangel config for base VM (btrfs, no encrypt)
- archsetup-vm.conf: archsetup config for unattended test execution
- assets/archangel.conf.example: reference archangel config

Deleted:
- finalize-base-vm.sh: merged into create-base-vm.sh
- archinstall-config.json: replaced by archangel .conf format

Tested: full end-to-end run — 51 validations passed, 0 failures.
