*Hacktoberfest 2025 - Documentation*

Start with the repository and README, then run TermiFlux on both x86_64 and ARM64 macOS environments to verify the documented workflow. Update the README with the overview, installation steps, usage examples, troubleshooting guidance, and screenshots or GIFs; the work is done when users can understand and use TermiFlux without further guidance.
