fix(drone): resolve drone feed fog and flicker issues

- Add preserveDrawingBuffer to enable automated test screenshots
- Neutralize scene fog during drone render pass to prevent misted aerial view
- Render drone feed every frame instead of alternating with ground view
- Update visor styling with scanline effect and improved borders
- Add debug getters for WebGL renderer and scene information

+## Fase 2 — Mundo 3D Jogável (Entregue)
+
+O visualizador `/city` carrega o mundo completo em tempo real:
+
+- **Cidade de 72 quarteirões** (grade 9 × 8 de blocos de 40 m; bounds
+  `−120..160 × −120..120`), com rio e ponte a oeste, extensão rodoviária ao
+  sul, casas de jogadores e um conjunto de lugares públicos com letreiros
+  luminosos: **hospital, escola, prefeitura, universidade, corpo de
+  bombeiros** (prédios cívicos) e **supermercado, drogaria, restaurante,
+  cabeleireiro, banco, hotel e shopping** (11 lojas no total, todas com
+  placa frontal + letreiro vertical blade).
+- **Trânsito**: carros, motos, bikes e ônibus com tráfego à direita, loop por
+  quarteirão e **semáforos por cruzamento** (fases NS/EW com amarelos e
+  all-red; veículos param na linha de parada **antes** das faixas).
+- **Faixas zebradas reais** (barras longitudinais paralelas ao fluxo, design
+  MUTCD) com calçadas e meio-fios interrompidos nas travessias — 323 faixas no
+  layout atual.
+- **Pedestres** com travessia sincronizada ao semáforo; bloqueio de travessia
+  do jogador no vermelho.
+- **Praças** (1 a cada 4 células) com academia externa: exercícios com pose,
+  efeito em saúde/energia e missão “Shape em dia”.
+- **Praia a leste** (`/city` + `App\Support\Beach`): areia, mar com ondas
+  animadas (deslocamento de vértices), espuma na orla, **banhistas, nadadores,
+  surfistas, salva-vidas (torre + patrulha), quadra de basquete com jogadores
+  e bola em arremesso, barracas de comidas, cadeiras e guarda-sóis**.
+  O jogador pode **relaxar na areia** (tecla `E` → `POST /city/actions/beach`),
+  recuperando energia/saúde por tick até o máximo.
+- **Dois aeroportos** derivados dos bounds (pavimento + sinalização de
+  pista com designadores, taxiways com eixo amarelo, pátio de embarque com
+  posições de estacionamento de aeronaves, terminal com pontes articuladas,
+  hangars, torre de controle e helipista): **7 aeronaves de 7 companhias**
+  (jato comercial, jato regional, monomotor e helicóptero) executam o ciclo
+  completo *taxi → decolagem → cruíse sobre a cidade → aproximação → pouso
+  → taxi → gate*, com contagem de decolagens/pousos em `stats().flights`.
+- **Torre de controle com IA**: o agente `atc` "Torre de Controle City10"
+  (modelo `AI_ATC_MODEL`, `poolside/laguna-xs-2.1:free`) gera clearances de
+  decolagem a cada decolagem (`POST /city/airport/dispatch`, cooldown de
+  30 s) numa **cadeia de modelos** `AI_ATC_MODEL` → default →
+  `AI_FALLBACK_MODEL` (`xiaomi/mimo-v2.6-flash`), com texto determinístico
+  quando tudo falha; o clearance mais recente aparece como aviso "✈ ...".
+- **Agentes vivos**: prefeito itinerante, lojistas nas lojas, pedestres com
+  rotas, mais trens (passagem de nível com barreiras), ônibus/trem
+  embarcáveis, avião e barcos no rio.
+- **Dia/noite e clima** com ciclo de horas, névoa, chuva e sombras que seguem
+  o jogador.
+- **Conversas de rua** com outros jogadores e NPCs (ver próxima seção).
+- **Performance**: *batching* estático por material, sombra seguindo o
+  jogador (janela ±120), lâmpadas/rodas com LOD por distância e fachadas a
+  256 px — medições ~30–60 fps numa GTX 770.
+
+### Controles
+
+| Controle | Ação |
+|---|---|
+| `W A S D` | Andar (A/D = lateral) |
+| Mouse (pointer lock) | Olhar; **arrastar na cena** quando sem lock |
+| `←` `→` | **Viram a câmera** (não andam de lado) |
+| Joystick virtual (mobile) | Vertical = andar, horizontal = **virar a câmera** |
+| `E` | Contexto: exercício na praça / relaxar na praia / parar |
+| `Espaço` | Pular |
+| Clique num NPC | Abrir chat |
+| Chegar perto de alguém | Chat abre sozinho; sai de perto ele fecha |
+
+---
+
+## Conversas de Rua (`/talk/person`) e IA por Personagem
+
+- **Registro por dia**: cada fala gravada em `person_talks`
+  (`from/to` de character ou agent + `talked_on` + `is_fallback`), consultável
+  via `GET /talk/person?kind=agent|character&peer=ID`.
+- **Fio da meada**: o histórico completo (dias anteriores + hoje) é enviado
+  como contexto nas respostas de IA — placeholders de erro (`is_fallback`)
+  ficam visíveis na UI mas **nunca** entram no contexto do modelo.
+- **Quem responde**:
+  - Par com **humano vivo** (sessão tocada nos últimos 5 min) → relay puro,
+    nunca é substituído por IA;
+  - Par **sem humano** (cidadãos demo, NPCs) → persona anônima de morador
+    responde via OpenRouter, sem dados cadastrais no payload.
+- **Resposta de IA** é gerada *after-response* (não depende de worker de
+  fila), com espaçamento por par, allow-list de modelos, fallback localizado
+  em falha e auditoria em `last_decision`.
+- **Identidade por personagem**: colunas em `characters` — `ai_model`,
+  `ai_age`, `ai_gender`, `ai_personality`, `ai_bio` (persona injetada no
+  prompt; recém-criados já nascem com personalidade/idade).
+- **Modelo por personagem** (ordem de resolução, sempre validado em
+  `allowed_models`): coluna `ai_model` → mapa `AI_CHARACTER_MODELS` (id ou
+  nome) → slot determinístico do pool `AI_MODELS` → `AI_DEFAULT_MODEL`.
