feat(agents): Implementar Fase 8 - Persona, Onboarding e Escalação Inteligente

PORQUE FOI FEITA ESSA ALTERAÇÃO?
Nova Funcionalidade. Implementação completa da Fase 8 conforme PRD:
- Módulo de Onboarding com saudação por horário e registro de usuários
- Integração do fluxo no TelegramClient
- Handler para não-clientes (modo Mensageiro Passivo)
- Threshold de confiança atualizado para 75% no Dispatcher
- Testes unitários para o módulo de Onboarding

QUAIS TESTES FORAM FEITOS?
- Lint: flake8 executado (warnings menores de whitespace)
- Unit Tests: pytest tests/test_onboarding.py passou com sucesso
- Verificação de imports e estrutura de modules

A ALTERAÇÃO GEROU UM NOVO TESTE?
Sim, criado tests/test_onboarding.py com cobertura para:
- get_time_greeting() em diferentes horários
- is_known_user() para usuários conhecidos/desconhecidos
- start_registration() e fluxo de pending
- Serialização/deserialização de UserProfile

-# Agente de Classificação Bancária (RAG + Llama 3.2)
+# Arthur - Agente de Suporte Técnico N2
 
-> **Branch:** `iris-classificacao-bancaria`
+> **Branch:** `arthur-suporte-tecnico-n2`
 
-Este projeto implementa um **Agente de IA especializado na classificação de transações bancárias** via API. Ele utiliza uma arquitetura **RAG (Retrieval-Augmented Generation)** com modelos locais otimizados para execução em **CPU**.
+Agente de IA soberano para Suporte Técnico N2, operando 100% local em CPU. Correlaciona dados em tempo real (Zabbix), histórico de eventos e bases de conhecimento técnico para fornecer diagnósticos precisos em ambientes multitenant.
 
 ## 🎯 Objetivo
-Classificar transações financeiras (ex: Pix, TED, Boletos) em categorias contábeis padronizadas, utilizando descrições históricas e aprendizado por similaridade.
+Automatizar a triagem e análise de chamados técnicos, oferecendo diagnósticos baseados em RAG e telemetria, com escalação inteligente para especialistas humanos quando necessário.
 
 ## 🏗 Arquitetura
 
-O sistema é construído sobre três pilares principais:
+```
-1.  **FastAPI (Python 3.12):** Exposição da API REST de alta performance.

+- O Arthur atua como "mensageiro" nesses casos, registrando o recado para a equipe.

 ## 🚀 Como Rodar
 
-### Pré-requisitos
-- Docker & Docker Compose
-- Python 3.12+ (Opcional, para rodar sem Docker)
-
 ### 1. Configuração
-Copie o arquivo de exemplo e ajuste as variáveis (se necessário):
 ```bash
 cp .env.example .env
+# Edite o .env com suas credenciais (Telegram, Zabbix, etc.)
 ```
 
-### 2. Executando com Docker (Recomendado)
+### 2. Executando com Docker
-O comando abaixo sobe a API e o Banco Vetorial:
 ```bash
 docker-compose up --build
 ```
-A API estará disponível em: `http://localhost:8000/docs`
 
-### 3. Executando Localmente (Dev)
+O bot estará online e monitorando mensagens do Telegram.
-Se preferir rodar o Python diretamente:
 
-1. **Suba apenas as dependências (Qdrant):**
+### 3. Executando Homologação
-   ```bash
+```bash
-   docker-compose up qdrant -d
+docker exec arthur_agent python -c "from src.deployment.homologation import run_homologation; import asyncio; asyncio.run(run_homologation('staging'))"
-   ```
+```
 
-2. **Instale as libs:**
+---
-   ```bash
-   pip install -r requirements.txt
-   ```
-
-3. **Rode a API:**
-   ```bash
-   uvicorn src.main:app --reload
-   ```

-## 🧠 pipeline RAG (Resumo)
+---
-1. **Input:** Recebe JSON da transação (`descricao`, `valor` ignorado, `tipo`).
+
-2. **Retrieval:** Busca 5 exemplos similares no Qdrant.
+## 📚 Documentação Adicional
-3. **Inference:** Llama 3.2 analisa a transação atual + exemplos.
+- [PRD Completo](.gemini/PRD_Suporte_Tecnico_N2.md)
-4. **Validation:** PydanticAI garante que a categoria retornada existe.
+- [Roadmap de Desenvolvimento](.gemini/TODO_Arthur.md)
-5. **Feedback:** Transações validadas alimentam o treino futuro.
