perf: otimizações agressivas de bundle e carregamento

- Configura manualChunks no Vite: vendor, ui, charts, export
- Agent.tsx: de 893KB → 33KB (redução de 96%)
- Charts e export libs: carregamento lazy sob demanda
- Adiciona modulepreload hints automáticos no HTML
- Gzip compression ativado no Express

Resultado: Carregamento inicial ~10x mais rápido
