Summary

• detect configured port bindings while a Docker database container is stopped
• start and re-inspect stopped containers so DBcooper uses Docker’s actual mapped host port
• wait for the database to become ready before saving the linked connection
• cover fixed and dynamically assigned stopped-container bindings with regression tests

Verification

• cargo test --lib -- --test-threads=1
• cargo test --no-run
• rustfmt --check --edition 2021 src/docker/cli.rs src/docker/service.rs
• bun run check
• live disposable PostgreSQL container: stopped configured 127.0.0.1:56432 to 5432, then started, re-inspected, and confirmed ready
