V55: Standalone Comments Module

Creates polymorphic comments tables decoupled from the Posts module. Comments can be attached to any resource type via resource_type + resource_id.

Tables

• phoenix_kit_comments — threaded comments with polymorphic resource association
• phoenix_kit_comments_likes — comment like tracking
• phoenix_kit_comments_dislikes — comment dislike tracking

Design

• Polymorphic: resource_type (varchar) + resource_id (uuid), no FK constraints
• Self-referencing parent_id for unlimited threading depth
• Counter caches for like_count and dislike_count
• Status-based moderation (published/hidden/deleted/pending)
• Old phoenix_kit_post_comments tables remain untouched
