This should detect any table which can be linked to the current table via some other table, based on the other table having a foreign key to them both.

These join tables could be arbitrarily complicated. They might have foreign keys to more than two other tables, maybe even multiple foreign keys to the same column.

Ideally M2M defection would catch all of these cases. Maybe the resulting inspect data looks something like this:

"artists": { ... "m2m": [{ "other_table": "festivals", "through": "performances", "our_fk": "artist_id", "other_fk": "performance_id" }]

Let's ignore compound primary keys: we k it detect m2m relationships where the join table has foreign keys to a single primary key on the other two tables.
