Fix Windows version detection and remove leftover debug logging

[AverWasTaken]

what changed

• fixed the Windows build check in final.bat
• Windows 10 installs now actually get the SOS 10 labels
• removed the leftover wallpaper debug logging from both the playbook and script

why

lowkey funny after the discussion on the last PR, but the playbook was literally shipping two blocks named agent log with hard-coded session and hypothesis IDs lol

the actual functional bug is that ver parsing returned the word Version, then fed that into a numeric comparison. even if that worked, both branches defined w11, so if not defined w11 could never select Windows 10.

impact

no tweak behavior changes. this just removes debugging leftovers and stops finalization from choking on the OS version check.

checks

• parsed all 9 YAML files
• parsed every top-level PowerShell script
• parsed playbook.conf as XML
• confirmed the corrected command extracts build 26200
• confirmed no debug instrumentation markers remain
• git diff --check
