Corrigir E2BIG em pipelines, adicionar diretório de projeto e retomada

- Instalar Claude CLI no container Docker (npm install -g)
- Pipar prompt via stdin ao invés de argumento -p (resolve E2BIG)
- Adicionar campo workingDirectory na criação/edição de pipeline
- Pre-preencher com /home/projetos/ como base path
- Auto-criar diretório se não existir ao executar agente
- Salvar failedAtStep e lastStepInput quando pipeline falha
- Implementar retomada de pipeline a partir do passo que falhou
- Adicionar botão Retomar no histórico para pipelines com erro
- Configurar trust proxy para Express atrás de reverse proxy
