[Documentation] README.md: Overhaul for Better Quality

[sz1kormar]

Summary

The current README.md provides a solid overview of the project, but its structure and presentation can be improved to better reflect the scale and capabilities of stable-diffusion.cpp. The documentation is dense in some areas, sparse in others, and could benefit from a clearer hierarchy, improved readability, and a more modern layout.

Benefits

• More intuitive onboarding for new users
• Clearer communication of project capabilities
• Easier maintenance and future updates
• More professional and modern presentation
• Better alignment with documentation standards used by major ML projects

To be honest, this looks like AI slop. Among other issues, it's replacing local documentation links with invalid Google searches.

@wbruna it is just a concept not an actual replacement because it is a rough sketch not intended to be used without refinement.

Here is a human written article instead about how this can be a good way to improve formatting.
