The linux-release preset inherited PLOT_BUILD_TESTS=ON, so the release build
compiled the pyramid cover/merge and ring upload/wait/slot counters into
libplot_core.a and cmake --install shipped them. Set PLOT_BUILD_TESTS=OFF in the
preset; the suite keeps running in linux-debug and linux-asan, which are
unchanged.
Also pin the two header properties the plan calls Global Constraints and that
nothing guarded: every header under include/plot/ compiles standalone, and
include/plot/plot.hpp includes every public one. tests/CMakeLists.txt globs the
headers at configure time (CONFIGURE_DEPENDS) and generates one TU per header
plus an umbrella TU that constructs Plot, Renderer, data::StreamSeries and
input::Controller; a ctest entry builds the header TUs and runs the umbrella,
and cmake/plot_umbrella_check.cmake fails configure and ctest when a public
header is missing from the umbrella.
