fix(template): make prepare-win robust without prior Deploy run

- WinRM MaxProcessesPerShell: apply 100 if below threshold before asserting
- DesktopHeap SharedSection: apply 4096 KB registry value if below threshold before asserting
- Replace cleanmgr (hangs in WinRM Session 0, no window station) with direct
  PowerShell cleanup for dumps, WER files and Recycle Bin; DISM already covers
  component store and WU cache
- vcpkg git clone/checkout: wrap with EAP=Continue to suppress PS5.1
  NativeCommandError on git stderr (gotcha #3 from AGENTS.md)
- template.py: filter CI_EXITCODE:N marker from displayed output
- ci-static-ip.ps1: switch from vmware-rpctool (removed in recent Tools) to
  vmtoolsd --cmd; use temp-file redirect to capture output from native cmd
