New `ci template deploy-win` builds the Windows Server 2025 template VM on
the Linux host, mirroring the legacy Deploy-WinBuild2025.ps1 ten-step flow
in Python:
- winimage/uup.py: resolve the newest (or pinned) WS2025 build via the
uupdump API and build a cached, MS-signed ISO via the uup converter.
- winimage/autounattend.py + assets/: render autounattend.xml and the
guest post-install.ps1 (ported from the PS heredoc; VMware Tools now
mounted as a 2nd CD, scanned at first logon).
- winimage/iso_patch.py: xorriso repack injecting the answer files at the
ISO root and swapping the EFI boot image to efisys_noprompt.bin
(no "press any key" prompt — essential for an unattended headless install).
- commands/template.py: the deploy-win command + _winbuild_vmx_lines
(the 82-key VMX), _remove_vmx_lines, _wait_install_flag, _vmrun_soft_stop.
Acquire → patch → VMDK → VMX → install → flag wait → strip media +
NIC e1000e→vmxnet3 → verify IP → cold snapshot.
Deterministic by build (--build), with --win-iso to bypass UUP. Tests
mirror the prepare-win mocking style; total coverage 93%.
