dotnet/csharplang ? reverse-engineered prompt

Build me a clean public documentation hub for the official C# language design repo. I want someone who is curious about the future of C# to land on the site and quickly understand where to find active feature proposals, language design meeting notes, language version history, the design process, and the spec material.

Use the markdown content that already exists in the repo as the source of truth. Make the home page welcoming and simple, with clear sections for proposals, meetings, version history, communities, and contribution guidance. The meetings should be easy to browse by year, and proposals should feel organized enough that readers can tell what is active, completed, or historical if the files make that clear.

Also include a clear explanation that new feature ideas should start as GitHub discussions, not pull requests, unless the language design team invites them. Keep the tone official but approachable. Look up current docs online if you need to.
