quinnyfoco-design/eightfetch — reverse-engineered prompt

Build me a tiny Rust command line tool called eightfetch that runs as 8fetch on Linux and prints a nice system summary in the terminal. I want it to feel like fastfetch or neofetch, with an ASCII Linux logo on the left and a clean bordered info box on the right.

It should show the basics people expect, like OS, kernel, device, uptime, packages, shell, desktop environment, terminal, resolution, CPU, GPU, RAM, and disk usage. Please make speed the main priority. Avoid calling lots of outside programs, read Linux system files directly where possible, and keep it to the Rust standard library if you can.

Add simple options for normal colored output, grey monochrome output, and a custom hex color like 8fetch color:5f5f5f. Make it build with Cargo, include a clear README with install and usage instructions, and keep the code clean enough that I can publish it as a small open source project.
