Assert-IsoStructure.ps1 reused a fixed mount dir; a prior aborted run left a WIM
mounted there, so Mount-WindowsImage failed with 'directory is not empty' and the
persist-to-stable-path step was skipped (no ISO deployed). Now discards stale mounts
+ clears corrupt mount points + uses a unique per-run mount dir (mirrors build.ps1
Stage 0), and removes the dir after. Also asserts apps/catalog.json baked into the WIM.

Implement build.ps1 (M2): mount/extract the base ISO, offline-service
install.wim (inject GPD drivers if staged, debloat appx, bake SetupComplete.cmd
+ hardening modules into \Windows\Setup\Scripts), inject autounattend.xml,
oscdimg UEFI repack, emit SHA-256 + SBOM. Elevation + oscdimg guarded.
Add .gitea/workflows/build-iso-windows.yaml: runs on the self-hosted
silverlabs-runner-win (windows-latest), ensures ADK Deployment Tools, acquires
the base ISO from repo var SILVERMETAL_BASE_ISO_URL or a pre-staged path, builds,
validates the baked payload offline, uploads SBOM/SHA (+ISO on dispatch/tag),
attaches to a Gitea release on win-v* tags. Mirrors build-iso-linux.yaml.
Add tests/Assert-IsoStructure.ps1: the no-nested-virt CI gate - mounts the built
ISO + install.wim read-only and asserts autounattend.xml, SetupComplete.cmd, and
the hardening modules are correctly baked. Full QEMU boot+Verify is a follow-on.
Switch autounattend to Windows' native SetupComplete.cmd auto-run (SYSTEM, end
of setup) instead of a duplicate FirstLogonCommands call.
Untested until first runner execution (dev box is ARM64). All PS parse-clean;
autounattend XML + workflow YAML valid.
