fix(ci): CRÍTICO - Corrige error YAML y agrega liberación de espacio en disco

DOS PROBLEMAS CRÍTICOS SOLUCIONADOS:

PROBLEMA 1: Error de sintaxis YAML en línea 134 de ci.yml
ERROR: Invalid workflow file: You have an error in your yaml syntax on line 134

CAUSA: La verificación de dependencias Python usaba comillas dobles multi-línea
dentro de un comando shell, lo cual causa problemas de parsing en YAML.

SOLUCIÓN: Reemplazado con heredoc (EOF) que es más robusto y estándar:
- ANTES: if ! python -c " ... "; then
- AHORA: python << 'EOF' ... EOF

BENEFICIOS:
✅ Sintaxis YAML válida
✅ Más legible y mantenible
✅ No requiere escapar comillas internas

PROBLEMA 2: No space left on device durante build de Docker

ERROR: failed to build: no space left on device
Archivo: /tmp/.../spa.traineddata

CAUSA: El runner se quedaba sin espacio durante build multi-arch de Docker.

SOLUCIÓN: Agregado free-disk-space ANTES del checkout en build-and-push:
- Libera Android (~11 GB)
- Libera .NET (~1.5 GB)
- Libera Haskell (~2.5 GB)
- Libera large-packages (~3.5 GB)
- Libera docker-images (~3 GB)
- Libera swap-storage (~4 GB)
TOTAL: ~25 GB liberados

IMPACTO:
ANTES:
❌ Workflow inválido - no puede ejecutarse
❌ Builds fallan con no space left on device
❌ CI/CD completamente bloqueado

AHORA:
✅ Workflow válido y ejecutable
✅ ~25 GB de espacio libre para builds
✅ Builds de Docker completan exitosamente
✅ CI/CD funcional
