Tests de humo para el MCP SAIJ + CI

[leocagli]

El conector componentes/mcp-saij/server.mjs no tiene tests. Mínimo viable:

• Test de humo de las 4 herramientas (saij_buscar_jurisprudencia, saij_buscar_legislacion, saij_buscar_doctrina, saij_documento) contra la API pública, tolerante a indisponibilidad (skip con warning).
• Validación del contrato de salida (campos: título, uuid, URL, extracto).
• GitHub Action semanal + badge en el README — también detecta cambios rompientes de la API de SAIJ.
