Gogh-Co/Gogh ? reverse-engineered prompt

Build me a simple terminal theme installer called Gogh that lets people browse a bunch of pretty color schemes and apply one to their terminal with one command.

I want it to work on Linux and macOS, with an easy interactive flow where the user picks a theme from a list, plus a way to install a specific theme directly if they already know the name. It should also have a non interactive mode so it can be used in scripts, dotfiles, or setup automation.

Make it support the common terminal apps mentioned in the project, and structure the code so the theme definitions and install logic are easy to extend later. Include clear setup and usage instructions, and if you need current terminal specific details, look them up online before wiring them in.
