Subject: [PATCH] Updated Win32 path macro handling in win32/zoitechat.props so
 local Your*Path values can now be sourced from environment variables
 (ZOITECHAT_DEPS_PATH, ZOITECHAT_GENDEF_PATH, ZOITECHAT_PERL_PATH,
 ZOITECHAT_PYTHON3_PATH, ZOITECHAT_WINSPARKLE_PATH) before falling back to the
 existing c:\gtk-build\... defaults. This makes CI/dev-shell overrides much
 easier without manually editing the props file each time. Added a new MSBuild
 target (ValidateWindowsBuildEnvironment) that runs before build prep and
 fails fast with explicit errors when GTK/GLib/OpenSSL headers or Python are
 missing, instead of allowing a long cascade of downstream compile/link/copy
 failures.
