wip: Windows desktop app scaffold (WinUI 3/.NET 8) + NSIS installer + docs

Owner decision pending (STATE.md DC-100 tick): adopt/ship/park. Preserved from fragile git stash to named branch 2026-08-23. NOTE: requires a Windows build machine (WinUI XAML compiler + MSIX do not cross-build on Linux) — see WINDOWS_APP_BUILD.md in this tree. Secret-scanned clean 2026-08-23 (no keys/tokens/PEM in tree).
