refactor(workflow): complete migration from JSON Script to n8n format

BREAKING CHANGE: MetaBuilder JSON Script v2.2.0 format is deprecated.
All workflows now use n8n schema exclusively.

Changes:
- Migrated all 133 .jsonscript files to standard .json format
- All workflows now conform to schemas/n8n-workflow.schema.json
- Removed 211 backup files created during migration
- Complete JSON Script to n8n schema transformation:
  * MetaBuilder nodes → n8n-compatible nodes with proper types
  * Custom parameters → standard n8n parameters
  * Edge arrays → adjacency map connections
  * Trigger objects → explicit triggers array
  * Single-file workflows → proper adjacency format

Impact:
✅ 100% of workflows now n8n-compatible
✅ First-class variable support via schema
✅ Complex DAG topology via adjacency maps
✅ Multi-tenant safety maintained throughout
✅ All business logic preserved
✅ Ready for n8n tooling, import/export, and execution engines

Architecture:
- Workflows stored in /packages/*/workflow/*.json
- Schema validation via schemas/n8n-workflow.schema.json
- Support for variables, credentials, triggers, connections
- TypeVersion pinning for backward compatibility

Migration is complete. Codebase is now 100% n8n-based.
Next step: Update workflow executor to use n8n execution engine.
