feat(matilda): administración de servidores — core + config + plan

matilda-core: modelo declarativo (Host, Container, VHost, Inventory).
matilda-config: renderiza Container→docker-compose/docker run y
VHost→bloque server nginx (con TLS + redirección :80→:443).
matilda-plan: reconciliación pura actual→deseado con acciones
ordenadas por dependencia (contenedores antes que vhosts, removes
en orden inverso). Demo CLI en apps/matilda.

29 tests. Funciones puras, cero Docker/SSH/disco.
