📝 Walkthrough

Walkthrough

The Comment model and database migration add spoiler flags and self-referential reply relationships. The create-comment DTO accepts optional validated isSpoiler and parentId fields. Comment retrieval now returns root comments with nested replies and reusable user and reaction selections, while explicitly excluding child comments from the top-level result.

Estimated code review effort: 3 (Moderate) | ~20 minutes
