feat: complete revolution architecture modernization

- Decoupled robust frontend into an Astro framework in `frontend/`.
- Replaced direct WebSocket broadcast with Smart Routing to distribute workload only to idle capable nodes, preventing 503 errors and duplicate responses.
- Rewrote WASM panic points (`unwrap()` handling) into panic-safe match blocks in qwen_coder.rs preventing Node Web Workers from crashing.
- Integrated robust dynamic Three.js 3D visualization.
- Resolved mermaid and THREE.js frontend hydration issues.
