The global .gitignore '*.exe' rule silently excluded netkvmp.exe + netkvmco.exe when the
NetKVM driver was committed, so only inf/sys/cat shipped. netkvm.inf REQUIRES netkvmp.exe
([SourceDisksFiles] + netkvmp.CopyFiles), so Add-WindowsDriver failed every build with 'the
driver package could not be installed' -> no virtio NIC driver -> no VM network. Un-ignore
windows/drivers/** and force-add the referenced binaries.

Add-WindowsDriver rejected the virtio NetKVM driver during offline servicing and
aborted the whole build. A driver issue must not brick the image: wrap it in try/catch
(warn + continue) and add -ForceUnsigned to bypass the offline-inject signature check
(the driver is WHQL-signed and loads at boot regardless). Add .gitattributes marking
driver/binary files as binary so the runner checkout never EOL-normalizes them.

The privacy hardening enables HVCI (Memory Integrity), which blocks the legacy
e1000 NIC driver (E1G6032E.sys) -> no network in the VM, so winget app installs
silently skip. virtio-net's NetKVM driver is WHQL-signed + HVCI-compatible. Staged
from virtio-win (w11/amd64) under windows/drivers/netkvm/; build.ps1 already auto-
injects any *.inf under windows/drivers/ into install.wim. Pair with a virtio NIC on
the VM (already switched). Lets apps actually install under hardening.
