Improve WASM Demo Website & Modernize CI

Overview

This PR significantly improves the ompparser WASM demo website's aesthetics and usability, giving it a modern "terminal-like" feel. It also modernizes the WASM CI workflow by removing outdated manual setup scripts.

Changes

🎨 Website Improvements (Visuals)

• Font Update: Switched to JetBrains Mono for a consistent, professional coding typeface.
• Dark Theme Polish:
  • Deepened background colors to #101112 for a better contrast.
  • Unified background colors between the main panel and the editor/log areas to verify the "split" look.
  • Sharpened border radii (4px) for a sleeker, hardware-terminal aesthetic.
• Visibility Fixes:
  • Fixed an issue where source code text was black on a dark background (now #f8f8f2).
  • Restored Syntax Highlighting colors that were previously masked.
  • Made the text cursor visible (white).
• Layout:
  • Fixed header alignment (forced 50px height).
  • Added an inline GitHub link with icon for better discoverability.

⚙️ CI Cleanup

• Simplify ci.yml: Removed verbose manual shell scripts for setting up the Emscripten environment.
• Modern Action: Relies purely on the mymindstorm/setup-emsdk@v14 action, which handles PATH and EMSDK environment variables automatically.

Verification

• Local UI: Verified locally; the site now looks cleaner and syntax highlighting works correctly.
• CI: The updated workflow should be verified by this PR's build checks.
