Clean up legacy documentation and scripts

- Remove all references to workflow execution/management features
- Delete legacy scripts for bidirectional n8n integration
- Update documentation to focus on node documentation serving only
- Remove old docker-compose files for workflow management
- Add simplified docker-compose.yml for documentation server
- Update CHANGELOG.md to reflect v2.0.0 and v2.1.0 changes
- Update Dockerfile to use v2 paths and database

The project is now clearly focused on serving n8n node documentation
to AI assistants, with no workflow execution capabilities.
