Subject: [PATCH] Install only public headers, not build2 metafiles

CMake's install(DIRECTORY include/) and Meson's install_subdir both
copied the include tree wholesale, dropping the build2 buildfile
metafiles (include/buildfile, include/geo/buildfile) into the
consumer's system include path. The build2 build itself never installs
them -- only these two rules did.

Restrict the CMake rule to FILES_MATCHING PATTERN "*.hpp" and add
exclude_files: ['buildfile'] to the Meson install_subdir. Both now
install exactly the eight public headers (detail/ preserved) and
nothing else. The build2 metafiles stay in the repo untouched;
header-only, no version change.
