feat(i18n): Spanish localization (phase 4)

Complete implementation of Spanish (es-419) language support:
- Canonical catalogs and data: messages/es.json, data/es/**, lib/data/es/**, public/exemplos/es/**
- Canonical slugs: /es/series, /es/catalogo, /es/comparacion, /es/componentes, /es/diagnostico, /es/frameworks, /es/glosario, /es/selector, /es/acerca
- Dedicated search index at /api/busca/es with Spanish accent normalization
- Strict exclusion of book references in Spanish routes and catalogs
- Language selector and root negotiation with es active (ENABLED_LOCALES = ['pt', 'en', 'es'])
- Extended verification suite: check-i18n, smoke-imagem and verifica-vazamentos
