Slice 1: Meson skeleton — kernel links wlroots 0.20 from C++, RMLUi 6.2 vendored
Root meson.build (C++23, WLR_USE_UNSTABLE, ccache-detected) with RMLUi 6.2
as a wrap-file tarball built through the cmake module (no git submodules —
settled decision) and doctest 2.5.2 from wrapdb. kernel unit: extern-"C"
wlr.hpp wrapper (with the C99 [static N] array-param workaround documented
in kernel.md), slice-1 probe contract, doctest suite (1/1 green). host-bin:
composition root printing versions, exit 0. tasks.md slice 1 done.
