Fetch the Boost CMake release archive (default 1.92.0) and build only
the libraries requested via find_package(Boost COMPONENTS ...), plus
their dependencies. Each component is exposed as Boost::<name>, e.g.
Boost::serialization. cmat now uses this module instead of a system
Boost install, so the Boost exercises are always available.
Also fix SolutionEx62Bonus: Employee.h used base_object without
including <boost/serialization/base_object.hpp>. This was not an
intentional exercise bug; it likely relied on a transitive include
in older Boost versions.

Comment out the loop that copied BASE_OPTIONS (minus -Werror) into
CMAT_OPTIONS so exercise targets no longer inherit the project
warning flags.

Add a CMakeLists.txt to each exercise directory, included from
cmat/CMakeLists.txt, so every exercise and solution becomes a buildable
target. GUI exercises link the curses-based DOS_Unix implementations on
Unix-like systems; the Windows-specific DOS variants are not compiled.
Exercises without a portable path or with missing dependencies (Boost)
are reported as not available at configure time.
Targets are excluded from the default build and built by name, e.g.
`cmake --build build --target Ex11`, so intentionally buggy exercises
such as Ex21 do not break the default build.
Also fix two portability issues: rename Ex11bug/pole.h to Pole.h for
case-sensitive filesystems and drop the extra Light:: qualification in
SolutionEx71A/Light.h. Document build commands and layout in AGENTS.md.
