feat: API Server — endpoints HTTP, OpenAI-compatible, Ollama, pi.dev

- server.py: API REST com 6 endpoints
- /health, /cora/score, /cora/dimensions, /audit/report
- /chat/completions (OpenAI-compatible)
- /verify (Cora V1-V7 verification)
- Auto-detecta Ollama, roda em qualquer PC
- CORS habilitado, resposta JSON, porta 8080

+API SERVER — OpenCode Ecosystem como servico HTTP
+Compativel com pi.dev, Ollama API, OpenAI API format.
+Roda em qualquer PC — sem dependencias alem de Python stdlib.
+
+Uso:
+  python server.py              # Inicia na porta 8080
+  python server.py --port 3000  # Porta customizada
+  python server.py --ollama     # Usa Ollama local como backend
+  python server.py --openai     # Usa OpenAI API como backend
+
+Endpoints:
+  GET  /health                  # Verifica se esta rodando
+  GET  /cora/score              # CORA-Score atual
+  GET  /cora/dimensions         # Scores por dimensao
+  POST /chat/completions        # OpenAI-compatible chat API
+  POST /verify                  # Verifica resposta com Cora V1-V7
+  GET  /audit/report            # Relatorio completo de auditoria
+  GET  /docs                    # Documentacao dos endpoints
