- Merge blockchain-node/.env.production into central /opt/aitbc/.env
- Update all blockchain paths to use standardized /var/lib/aitbc/ structure
- Remove separate .env.production file (merged into central config)
- Update systemd services to remove references to .env.production
- Standardize Coordinator API paths and RPC port (8006)
- Add trusted_proposers setting for follower nodes
- Update multi-node workflow to reflect merged configuration
- Use aitbc1genesis as default proposer in central .env
- All services now use single central .env file with standardized paths
This eliminates configuration file duplication and ensures consistent
directory structure across all AITBC services.
