"""project rule + topic suppressions

Revision ID: 0060
Revises: 0059
Create Date: 2026-06-01

Lets a project mute specific rules or whole topics from rulebooks it
subscribes to, without unsubscribing the rulebook. Two pure many-to-many
association tables; FKs CASCADE so removing a project / rule / topic
cleans the suppression rows automatically.
