- Go module path: casera-api -> honeydue-api
- All imports updated (130+ files)
- Docker: containers, images, networks renamed
- Email templates: support email, noreply, icon URL
- Domains: casera.app/mycrib.treytartt.com -> honeyDue.treytartt.com
- Bundle IDs: com.tt.casera -> com.tt.honeyDue
- IAP product IDs updated
- Landing page, admin panel, config defaults
- Seeds, CI workflows, Makefile, docs
- Database table names preserved (no migration needed)
