Replace nginx with ASP.NET Core static file hosting

- Move Astro source files into astro/ subdirectory
- Add ASP.NET Core app (Docs.Web) to serve Astro static output with caching, compression, trailing-slash redirects, and custom 404 handling
- Add build.cs script with targets: astro-build, dotnet-build, container, aspire, link-check, verify-formatting, clean
- Containerized Astro build (node:22-slim) for cross-platform consistency
- Dockerfile-free container publishing via dotnet publish /t:PublishContainer targeting aspnet:10.0-alpine
- Add .NET Aspire orchestrator (Docs.AppHost) for local dev
- Remove Dockerfile, .dockerignore, deployment/ (nginx configs), build.sh
