Subject: [PATCH] ci: same CMake build on Windows UCRT64

Linux alone would leave the platform where portability actually breaks
untested -- and it is the one the dead qmake workflow was aimed at.

Same standalone build as the Ubuntu job, same RS_* option set, so a failure on
one and not the other means a portability problem rather than a difference in
what was configured. What differs is what has to: pacman instead of apt, and the
two -include flags the super-project's Windows job also carries, since librnp
uses strlen and the fixed width integer types without including <cstring> and
<cstdint>, which this toolchain refuses.

No Qt packages here: this repository builds no GUI.

macOS is deliberately left out for now. Its counterpart in the super-project is
mostly Homebrew flag harvesting for Qt5, ffmpeg and speex -- GUI and VOIP
dependencies that libretroshare does not use -- so it would be a rewrite rather
than a transposition, with little to catch that Linux does not.

+# Windows (MSYS2 / UCRT64) CMake CI for libretroshare on its own.
+#
+# Same standalone build as ubuntu-cmake.yml: libretroshare has its own top level
+# CMakeLists.txt and pulls rnp, OpenPGP-SDK, BitDHT, rapidjson, restbed and
+# udp-discovery-cpp through FetchContent, so no super-project and no submodules
+# are involved. Only the MSYS2 packages below are installed.
+#
+# Windows earns its own job rather than a matrix entry: it is where portability
+# breaks first, its dependencies come from pacman rather than apt, and it needs
+# the two -include flags below, which the super-project's Windows job also
+# carries -- librnp uses strlen and the fixed width integer types without
+# including <cstring> and <cstdint>, which this toolchain refuses.
