Headless editor logic tests

Runs the editor's real command / picking / camera / tool code (editor.cpp, viewport.cpp, render.cpp) against no-op raylib and Dear ImGui back-ends (stubs/ + impl.cpp), driving it with a scripted mouse. No GPU or window needed, so it also works in CI.

cmake -B build -DHPP_BUILD_EDITOR_LOGIC_TESTS=ON && cmake --build build --target test_editor_logic
ctest --test-dir build -R editor_logic --output-on-failure

Linux + GNU ld/lld only (it links with --unresolved-symbols=ignore-all so UI-only code paths may stay unresolved). The stubs mirror the raylib 5.5 / ImGui 1.91 signatures the editor uses; they are not a re-implementation - they only exist so this code can be compiled and exercised without the real libraries.
