Revamp the DynLex website

[JohnHeikens]

What changed

• Replaced the old animated marketing homepage with a responsive, editorial compiler-first design.
• Put programmable patterns, static inference, LLVM/native/WASM/SPIR-V targets, LSP/DAP tooling, practical validation programs, platform support, and current project status on the homepage.
• Added interactive, keyboard-accessible code examples that open directly in the browser IDE.
• Added responsive navigation, reduced-motion support, no-JavaScript fallbacks, print handling, structured metadata, and clear focus states.
• Removed the unused C++/Python comparison screenshots and unsupported absolute performance claims.
• Added Pages-time checks for required project information, local links, structured metadata, accessibility hooks, interaction wiring, and obsolete copy.

Why

The previous page emphasized a long WebGL intro and broad marketing claims while hiding much of the information developers need to evaluate DynLex. This version leads with the language model, shows how compilation works, demonstrates what exists today, and stays explicit about the project being an early release.
