feat: add comprehensive update script for n8n dependencies

- Created update-and-publish-prep.sh script that automates entire update process
- Script now runs all 1,182 tests before allowing updates
- Automatically bumps version and updates README badges
- Integrates with npm publish preparation workflow
- Added 'npm run update:all' command for one-step updates
- Updated MEMORY_N8N_UPDATE.md with new comprehensive process

The new workflow ensures:
- All tests pass before version bump
- README badges stay in sync
- Consistent commit messages
- Ready for npm publish after update
