 `pgd` manages Docker containers with PostgreSQL images. Each project's container is named deterministically based on the project directory name, ensuring no duplicates.
 
 The tool tracks state separately for each instance to detect configuration drift, such as:

 - Version mismatches between `pgd.toml` and the running container
 - Port conflicts or changes
 - Container state inconsistencies
