- Removed standalone test executables (`test_undo`, `test_buffer_save`, `test_buffer_open_nonexistent_save`, etc.). - Introduced `kte_tests` as a unified test runner. - Migrated existing tests to a new minimal, reusable framework in `tests/Test.h`. - Updated `CMakeLists.txt` to build a single `kte_tests` executable. - Simplified dependencies, reducing the need for ncurses/GUI in test builds.
