feat(cmat): add cmake build for course material

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. Co-authored-by: Qwen 3.8 27B <qwen3.8_27b-q3_k_xl@lmstudio.local>
