build: Update build system for terminal browser

Update CMake and add Makefile for the new project:
- Rename project from NBTCA_TUI to TUT
- Update executable name from nbtca_tui to tut
- Add all new source files to build
- Include Makefile for environments without CMake
- Update .gitignore for build artifacts

Both CMake and Make build systems are now supported
for maximum compatibility.
