feat(home): prova no topo, contato sem atrito e conversão medida

Home mais curta (hero, vitrine de clientes, sobre, serviços, IA resumida, depoimentos e contato), faixa de clientes e telas reais no hero, sem números do GitHub. Barra de cookies fina, WhatsApp fixo no celular, formulário com e-mail opcional e alternativa por e-mail, página /ia, eventos de e-mail, redes e currículo e conversão do Ads opcional por variável. Rodapé em 3 colunas. Remove componentes órfãos (LighthouseMetrics, Skills, Experience, contagem do GitHub).
