This commit introduces a more reliable and consistent approach to setting up the development environment using backups: - Add setup-from-backup.sh script for environment setup from existing backups - Standardize script naming and organization - Move obsolete scripts to bin/obsolete directory - Update documentation with new workflow instructions - Create migration guide for transitioning to new workflow - Update Memory Bank with workflow improvements The new workflow provides: - More reliable environment setup - Faster setup process - Offline development capability - Consistent development environments across team members Breaking changes: - setup-dev.sh is replaced by setup-from-backup.sh - sync-and-setup.sh is replaced by separate scripts - verify-with-wpcli.sh is no longer used Migration path is documented in MIGRATION_GUIDE.md
