V3 CLI: ability to track relationship from one or more Foreign Keys

If I track a table one by one using CLI, I have to track relationships manually.

Request to add ability to track relationships for these tables based on foreign keys automatically on a single track table.

Start at the V3 CLI entry point for tracking a single table and trace how foreign-key relationships are currently handled. Define expected behavior for tables with one or more foreign keys, including how automatically discovered relationships are reported, then add or update CLI coverage to verify the result.
